Question

Why do covalent bonds need a pair of electrons?

Answer 1

hey mate ur ans

as covalent bond is bond formed due to share of electron so it requires pair of electron
actually when two of non metal have 456 electron so it difficult to tr!nsferq so they share electrons

Answer 2

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a fullelectron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.
