Question

Ferromagnesium silicates contain the elements

Answer 1

Ferromagnesium silicates contain the elements:(( silicon, oxygen, iron, and magnesium))

Step-by-step explanation:

Ferromagnesium silicates in which iron and magnesium form the major structure of silicates and silicon and oxygen are present in silicates.

They are dark in color because of the presence of elements like iron and magnesium.

The specific gravity of Ferromagnesium Silicates is higher as compared to non Ferromagnesium Silicates.

Examples of Ferromagnesium silicates are pyroxene, amphibole, olivine, Garnet and biotite.

Answer 2

The correct answer is silicon (SiO4), oxygen (O2), iron (Fe) and magnesium (Mg).

Ferromagnesium silicates are minerals in which cations of iron and magnesium form essential chemical components on the silicate structure (contains SiO4 tetrahedra). The minerals from this group include the olivines, pyroxenes, amphiboles, and the micas biotite and phlogopite.
