Question

Silicate minerals contain the elements silicon and oxygen. what contains only silicate materials

Answer 1

Silicates are minerals that contain silicon atoms bonded to oxygen atoms. The basic building block for all silicate minerals is called a tetrahedron, where onesilicon atom is bonded to 4 oxygen atoms. Silicate minerals also often contain other elements, such as calcium, iron, and magnesium.

Answer 2

Answer:

Potassium feldspar, Amphibole and Quartz

Explanation:

Silicate minerals are the important rock-forming minerals as they are highly abundant in the earth's crust. They are also found in large quantities in the mantle. It is comprised of both silicon and oxygen, where the four oxygen atoms are linked to a Silicon atom at the center, forming a covalent bond. The rocks formed from this mineral are very hard and resistant.

The minerals such as potassium feldspar, amphibole, and quartz are comprised of a large amount of silicate minerals.
