Elements that occur in nature as minerals in uncombined form
Native copper Native gold Native silver Native sulfur Diamond (native carbon)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 Nickel–Strunz classification system also includes the naturally occurring phosphides , silicides , nitrides , carbides , and arsenides .
Elements The following elements occur as native element minerals or alloys:[1]
