Question

Silicon is found in nature in the forms of ________

(a) body-centered cubic structure

(b) hexagonal-closed packed structure

(c) network solid

(d) face-centered cubic structure

I have been asked this question in homework.

My doubt stems from Amorphous and Crystalline Solids in section Solid State of Chemistry – Class 12

Answer 1

The correct choice is (c) network solid

The explanation is: Silicon due to its catenation property form network solid. Catenation is the ability of an atom to form bonds with other atoms of the same element. The compounds of silicon are reactive and not stable.
