Ex: Magnesium – one magnesium atom loses 2 electrons to achieve the inert gas electron configuration, therefore, the valency of magnesium is 2(or +2). Covalency from atomic contribution to the electronic density of states. Recall that covalency is the number of shared electron pairs formed by an atom of that element. It is equal to the number of electrons the atom loses, or gains or shares when it combines with one or more atoms. Covalency definition is - covalence. Add your answer and earn points. Relevance.
