Concept introduction:
Ionic charge is defined as the charge possesses by an ion that result by the gain or loss of an electron by an atom or a molecule. Metals are electropositive in nature because they loss electrons from their outermost shells. Nonmetals are electronegative in nature because they gain electrons in their outermost shells.
