WebThe simplest silicate structure, that of the mineral olivine , is composed of isolated tetrahedra bonded to iron and/or magnesium ions. In olivine, the −4 charge of each silica tetrahedron is balanced by two divalent (i.e., +2) iron or magnesium cations. Olivine can be either Mg 2 SiO 4 or Fe 2 SiO 4, or some combination of the two (Mg,Fe) 2 SiO 4. WebThe most common native metals, which are characterized by simple crystal structures, make up three groups: the gold group, consisting of gold, silver, copper, and lead; the platinum group, composed of platinum, palladium, iridium, and osmium; and the iron group, containing iron and nickel-iron.
