Native elements are among the most fascinating minerals in geology — chemical elements that occur in nature in their native form, meaning they are found in their pure, uncombined state. These remarkable substances formed the foundation of early human metallurgy and remain vital to modern industry. This guide is designed for geology students, mineral collectors, and anyone interested in Earth sciences, providing essential knowledge about native elements and their significance in both natural history and modern industry.
What are native elements? (fast answer)
Native elements are defined as chemical elements that occur in nature uncombined with other elements, excluding atmospheric gases.
Native elements are chemical elements found in nature in an uncombined, elemental state, forming minerals composed of a single element or simple natural alloys. Unlike atmospheric gases such as nitrogen and oxygen, native element minerals exist as solids or liquids within rocks, ores, and sediments.
-
Only about 20–30 of the 118 known elements on the periodic table occur naturally as native minerals
-
There are 24 known native elements, which are classified into three groups: metals, semimetals, and nonmetals.
-
Native elements are grouped into three groups: metals (gold, silver, copper, platinum), semimetals (arsenic, antimony, bismuth), and nonmetals (sulphur, carbon as diamond and graphite)
-
Many were among the first metals used by humans because they could be worked without smelting or complex refining techniques
-
Elements like native gold and native copper are chemically inert enough to persist uncombined in geological environments
-
These elements occur naturally in uncombined forms, often as metals, alloys, or nonmetals with specific mineral structures.
Formal definition of a native element mineral
A native element mineral is a naturally occurring, inorganic solid with an ordered crystalline structure and a chemical composition consisting of a single element or a simple natural alloy.
-
To qualify as a mineral, the substance must exhibit crystallinity, ruling out amorphous organic materials like amber or peat
-
Native element minerals may contain trace impurities — silver in gold forming electrum, or iron in platinum — but are classified by the dominant element
-
These minerals are distinct from more complex minerals and compound minerals such as oxides (hematite), sulphides (galena, pyrite), and silicates (quartz)
-
The term “native elements” sometimes extends informally to substances like petroleum and coal, though strict mineralogical usage is narrower
Classification of native elements: metals, semimetals, and nonmetals
Mineralogists traditionally divide native elements into three broad categories based on their physical and chemical properties: native metals, native semimetals, and native nonmetals.
Native Metals:
-
Metallic lustre, high electrical and thermal conductivity, malleability and ductility
-
Typically crystallize in close-packed structures (often cubic)
-
Common examples: gold (Au), silver (Ag), copper (Cu), platinum-group metals (Pt, Ir, Os, Pd, Rh, Ru), native iron (Fe) in meteorites, and mercury (Hg) as a liquid metal
Native Semimetals (Metalloids):
-
Intermediate properties between metals and non-metals, often brittle with metallic to sub-metallic lustre
-
Examples: arsenic (As), antimony (Sb), bismuth (Bi), sometimes tellurium (Te)
Native Nonmetals:
-
Generally low conductivity, nonmetallic lustre (except graphite with its metallic sheen), often brittle
-
Examples: native sulphur (S), carbon as diamond and graphite, and occasionally selenium (Se)
Some classification schemes also include related simple compounds — carbides, nitrides, phosphides, and silicides — alongside native elements for convenience.
Classification of native elements on the periodic table
Native elements are unique among minerals because they occur in nature in their pure form, uncombined with other elements. On the periodic table, these elements are scattered across different groups and periods, but their classification is based on both their chemical properties and the way they naturally occur. Mineralogists divide native elements into three main groups: native metals, native semimetals, and native nonmetals.
Native metals—such as native gold, native silver, and native copper—are often found in the same column or group on the periodic table, sharing similar properties like high density, metallic lustre, and chemical inertness. For example, native gold (atomic number 79) is famous for its pale yellow colour and is typically found in quartz veins and placer deposits, while native silver (atomic number 47) often occurs in sedimentary rocks and hot springs. Native copper (atomic number 29) is another classic example, recognized for its reddish hue and occurrence in both igneous and sedimentary rocks.
Native semimetals (or metalloids), including arsenic (atomic number 33) and antimony (atomic number 51), occupy positions near the metals on the periodic table but display a mix of metallic and nonmetallic properties. These elements are usually more brittle and have lower densities than true metals. Native arsenic, for instance, is found in both igneous and sedimentary rocks and is known for its metallic sheen but brittle nature.
Native nonmetals—such as native sulphur and native carbon—are found in different groups on the periodic table and are characterized by low density and higher chemical reactivity. Native sulphur (atomic number 16) is easily recognized by its bright yellow colour and is commonly found in salt domes, sedimentary rocks, and around hot springs. Native carbon occurs as diamond and graphite (atomic number 6), each with dramatically different properties due to their crystal structures along the c-axis: diamond is renowned for its hardness and clarity, while graphite is soft, dark, and greasy.
The classification of native elements on the periodic table is not just academic—it helps geologists and mineral collectors identify these minerals in the field and understand their formation. For example, native platinum (atomic number 78) is mined from igneous rocks and is essential in catalytic converters, while native iron, though rare on Earth, is found in meteorites and was among the first metals used by humans.
Native elements are also distinguished by their metallic lustre, a direct result of their chemical properties. Native metals typically shine with a bright metallic lustre, whereas native nonmetals such as sulphur have a more resinous or dull appearance. The c-axis in minerals such as graphite and diamond further helps mineralogists distinguish between different forms of the same element.
Understanding where native elements fall on the periodic table—and how their atomic number, group, and properties relate—provides valuable insight into their occurrence, mining, and uses. Whether it’s native zinc, native iron, or native platinum, these elements are not only fascinating from a scientific perspective but also play a crucial role in global industries, from jewelry and electronics to construction and energy.
Native elements in the Nickel–Strunz system
The Nickel–Strunz mineral classification places native elements in Class 1 (“Elements”), labelled “01” in databases like mindat.org, and sits alongside other mineral classification systems based on chemistry and crystal structure.
-
01.A Native metals and intermetallic alloys: Au, Ag, Cu, Pt, iron–nickel alloys in meteorites
-
01.B Native semimetals: As, Sb, Bi (arsenic group)
-
01.C Native nonmetals: S, C as diamond and graphite, Se
The 10th edition extends this class to include structurally similar compounds such as cohenite (Fe₃C) and moissanite (SiC). Field geologists typically use the simpler metals/semimetals/nonmetals subdivision.
Comprehensive list of native elements (with descriptions)
Gold (Au) – native metal with its distinctive yellow colour, symbol Au, and a density of 19.33 grams per millilitre (g/cm³), soft (Mohs 2.5–3). Major deposits occur in South Africa’s Witwatersrand Basin, the Canadian Shield (Ontario, Québec, Nunavut), Russia, and Australia. Gold can form in hydrothermal veins and is often associated with quartz and pyrite, and it can also be found in placer deposits in river beds. A gold nugget from placer deposits or quartz veins remains prized for jewellery, bullion, and electronics. Gold is used as a world monetary standard and in jewellery, dental fillings, and various scientific applications.
Silver (Ag) – native silver appears white but tarnishes dark; density 10.5 g/cm³. Important occurrences include the historic silver rush in Cobalt, Ontario (1903), as well as those in Germany, Mexico, and Canada. Uses span electrical contacts, jewellery, antimicrobial applications, photographic film, silverware, and electronic equipment.
Copper (Cu) – reddish native copper often develops green malachite coatings; density 8.9 g/cm³. Classic deposits occur at Michigan’s Keweenaw Peninsula and in British Columbia. Essential for wiring and alloys like bronze and brass, and valued for its high electrical conductivity.
Native Platinum (Pt) – steel-grey, dense (21.5 g/cm³), often alloyed with palladium or iron. Major placer deposits exist in Russia’s Ural Mountains and South Africa’s Bushveld Complex. Critical for catalytic converters and fuel cells. Platinum is also used as a catalyst to control automobile emissions and in jewellery and dentistry.
Platinum-Group Metals (Ir, Os, Ru, Rh, Pd) – occur as natural alloys like iridosmine associated with platinum and gold. Exceptionally hard with high melting points; used in catalysts, specialty alloys, and electronics.
Native Iron (Fe) – rare terrestrially but abundant in meteorites as kamacite and taenite. Québec’s Pingualuit crater provides a Canadian context. Indigenous peoples, including Inuit, used meteoritic iron before modern metallurgy.
Nickel (Ni) – occurs in iron–nickel alloys (awaruite) found in ultramafic rocks in British Columbia. Used in stainless steel and batteries.
Mercury (Hg) – liquid at room temperature; occurs with cinnabar deposits in Spain and California. Historically used in thermometers but now restricted due to toxicity.
Arsenic (As) – semimetal, tin-white when fresh, tarnishes grey; brittle with similar properties to other metals. Associated with silver and cobalt ores in Germany’s Erzgebirge and Cobalt, Ontario. Highly toxic; historic pesticide use.
Antimony (Sb) – silvery-grey, brittle semimetal; occurs with stibnite in China and Bolivia. Used in flame retardants and lead–antimony battery alloys.
Bismuth (Bi) – silvery-white with pinkish tint; soft with good cleavage. Found in hydrothermal veins in Bolivia and Peru. Used in pharmaceuticals and cosmetics.
Tellurium (Te) – brittle, silvery-white semimetal; sometimes found native but more often in telluride minerals with gold. Used in solar cells.
Sulphur (S) – native sulphur, symbol S, is commonly yellow and has a density of 2.05 to 2.09 grams per millilitre. Occurs around volcanoes, hot springs, and in caprocks above salt domes. Bacterial reduction of hydrogen sulphide contributes to sulphur formation, especially in geochemical environments such as hydrothermal deposits and mineral concentration zones. Sulphur is used for the manufacture of sulfuric acid, insecticides, hydrogen sulphide, and rubber. Essential for sulfuric acid production.
Diamond (C) – extremely hard (Mohs 10), typically colourless. Forms deep in Earth’s mantle and reaches the surface via kimberlite pipes. The Northwest Territories’ Ekati (1998) and Diavik (2003) mines represent world-class Canadian deposits and join other notable gemstone deposits in Canada. Used as gemstones and industrial abrasives. Diamonds are essential for cutting tools and abrasives due to their extreme hardness.
Graphite (C) – graphite is another form of carbon, soft (Mohs 1–2), dark grey to black, with a greasy feel, streaks grey, and has a density of 2.09 to 2.23 grams per millilitre. Commonly found in metamorphic rocks, graphite is typically found in metamorphosed coal deposits and can also occur in igneous rocks and meteorites. Deposits in Ontario and Québec supply battery and refractory materials. Graphite is used as a lubricant in oil, as a writing tool, and in paints, batteries, and refractory crucibles. Shares the same column on the periodic table as diamond, but has dramatically different properties due to its layered structure along the c-axis.
Selenium (Se) – rare native nonmetal forming in sulphide deposits and volcanic fumaroles (Chile). Used in glassmaking and electronics.
Borderline Native Substances:
-
Coal – organic rocks rich in carbon from Carboniferous-era plant remains; major deposits in Alberta, Saskatchewan, and Nova Scotia
-
Petroleum and natural gas – complex hydrocarbon mixtures; excluded from strict native element mineral classification
-
Amber – fossilized tree resin found near Cedar Lake, Manitoba; organic, not a native element
The atomic structures of native metals such as gold, silver, and copper are typically cubic, whereas those of native nonmetals such as graphite and diamond are different.
Geological formation and environments of native elements
Native elements form across diverse geological settings, from mantle depths to volcanic fumaroles and sedimentary rocks.
Hydrothermal Veins: Hot fluids deposit native gold and native silver in quartz veins cutting through igneous rocks and schists — notably in Ontario’s Timmins and Red Lake camps within the Abitibi Belt.
Magmatic Settings: Platinum-group metals crystallize from mafic–ultramafic magmas in layered intrusions like South Africa’s Bushveld Complex.
Placer Deposits: Dense native metals become concentrated in stream gravels through mechanical weathering. The Klondike Gold Rush (1896–1899) exploited Yukon placers yielding 20 million ounces.
Volcanic Deposits: Native sulphur precipitates around active volcanoes like Mount Etna, where fumarolic gases meet cooler air.
Evaporite Settings: Sulphur forms in caprocks above salt domes through bacterial sulphate reduction.
Deep Mantle Origin: Diamonds crystallize at depths exceeding 150 km under extreme pressure (>5 GPa) and travel upward in kimberlite eruptions.
Metamorphic Rocks: Graphite forms when organic-rich sediments undergo regional metamorphism, as in Québec’s Grenville Province.
Extraterrestrial Origins: Native iron–nickel alloys in meteorites represent differentiated asteroid cores and were used by cultures worldwide before zinc, lead, and other metals were smelted.
Economic importance and uses of native elements
Native elements underpin major global industries, including several key Canadian mining sectors.
Precious Metals: Gold serves as bullion, an investment, and jewellery — Canada ranks as the fifth-largest producer at 200 tonnes annually, with mines such as Detour Lake (Ontario) and the historic Klondike. Silver remains essential for electronics and antimicrobial uses.
Platinum-Group Metals: Critical for catalytic converters, reducing automotive emissions since the 1970s, plus fuel cell technology.
Base Metals: Copper drives electrical systems and renewable energy infrastructure; Highland Valley Copper in BC exemplifies Canadian production.
Nonmetals: Sulphur produces sulfuric acid for fertilizers. Canadian diamonds from Ekati, Diavik, and Gahcho Kué have generated over $12 billion since 1998. Graphite supplies lithium-ion batteries with 40% demand growth projected.
Environmental Considerations: Arsenic and mercury toxicity require strict controls; acid mine drainage from associated sulphides drives Canadian environmental regulations.
Properties that distinguish native elements from other minerals
Native elements display varied physical properties but share a key feature: composition of a single chemical element.
-
Metallic behaviour: Gold, silver, copper, platinum, and iron show metallic lustre, high conductivity, malleability, and ductility from delocalized electrons
-
Nonmetallic behaviour: Sulphur and diamond show poor conductivity and brittleness; diamond’s exceptional hardness stems from strong covalent bonds
-
Crystal structures: Gold, silver, and copper form face-centred cubic structures, allowing easy deformation; diamond versus graphite demonstrates how the same element with different bonding creates extreme property differences
-
Field identification: Gold maintains its yellow streak without tarnishing; silver tarnishes black; graphite leaves dark grey marks
-
Density: Native metals — especially gold (19.3 g/cm³) and platinum (21.5 g/cm³) — are remarkably heavy, causing them to concentrate in placer sediments
Compared with compound minerals, native elements have simpler compositions yet can form complex solid solutions, such as electrum (a gold–silver alloy).
