Correct answer choice is :
B) Oxygen and silicon
Explanation:
Silicates comprise silicon molecules and oxygen atoms. One silicon atom is bonded to four oxygen atoms. These atoms form a tetrahedron. The silica tetrahedron is the raising block of silicate crystals. This performs silicon more or less still to more oxidation by air even up to about 900°C. After this, reaction with oxygen in the air produces silicon dioxide. At temperatures above about 1400°C, silicon responds with nitrogen, N2, in the air as well as oxygen, to make the silicon nitrides SiN and Si3N4.
Answer: The correct answer is option (B).
Explanation:
The minerals are natural occurring inorganic solids with fixed chemical compositions with constituent atoms placed in an orderly pattern.
90% of earth crust is composed of a mineral made up silicates. And these silicates are the chemical compounds made up of silicon and oxygen element. They are also known as silicon tetra-oxide with chemical formula of [tex]SiO_4[/tex].
Hence, the correct answer is option (B).
