Question

what is the answer for this Ques
Why does carbon forms only covalent bonds?​

Answer 1

Answer:

Explanation:

Carbon has 4 electrons in its outermost shell.

In order to complete its octet i.e., 8 electrons in outer shell and to stabilize itself, carbon can either lose 4 electrons or gain 4 electrons.

However, this requires lots of energy and would make the system unstable.

Therefore, carbon completes its octet by sharing its 4 electrons with other carbon atoms or with atoms of other elements and forms covalent bond.

It forms strong covalent bonds because of its small size
