atoms lose electrons and non-metals gain electrons in order to achieve electron stability. When dealing with bond formation (Ionic bonding for example) we need to analyse the outer shell of the atom. Metals usually present 1‚ 2 or 3 electrons in their outer shell therefore they have to give them away to achieve stability. Vice versa non-metals have 5‚ 6 or 7 electrons in their outer shell and they need to receive more electrons in the outer shell to be stable. 1.2 Ionic bonding occurs between metal
