It is the number of electrons an atom of an element can gain,lose or share. The valency of an atom is equal to the valence electrons, if it is 4 or less. If it is more than 4, the valency is equal to 8 minus the number of electrons in the outer shell. Example: Magnesium has electronic configuration 2,8,2.
