Explanation:
The number of electrons that are shared, lost or gained by an atom during a chemical reaction is called as the valency of the element. The outermost shell of the atom is called the 'valence shell' and the electrons present in that shell are called the 'valence electrons'.Neon's valency is 0 and it's valence shell has 8 electron.
