Native element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure. The elemental class includes metals, intermetallic compounds, alloys, metalloids, and nonmetals. The NickelâÂÂStrunz classification system also includes the naturally occurring phosphides, silicides, nitrides, carbides, and arsenides.
