How are covalent bonds formed ?
Answer
A covalent bond forms when two atoms share a pair (or pairs) of electrons.
Covalent bonds are formed by the sharing of a pair (or pairs) of electrons between two atoms. The shared pair is attracted by both nuclei and counts towards the outer shell of each atom, so both atoms attain a stable, completely filled outer shell without any electron being transferred.
