In chemistry and physics, a valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed. In a single covalent bond, a shared pair forms with both atoms in the bond each contributing one valence electron.
Valence is the number of electrons an atom must lose or gain to attain the nearest noble gas or inert gas electronic configuration. “Electrons in the outer shells that are not filled are called valence electrons”.
