An element of group (II) loses two electrons in the process of a chemical combination. its ionic charge is + 2.
The group (II) element are the alkaline earth metals. metals have tendency to donate the electrons and form cation . the group (II) metal element have tendency to loose 2 electrons and for cation with ionic charge of +2. example :
beryllium atomic number is 4 . electronic configuration is 1s² 2s² it can loose and form Be⁺² , electronic configuration is 1s².
Thus, An element of group (II) loses two electrons in the process of a chemical combination. its ionic charge is + 2.
