Nature of bonding | metals | metalloids | ionic | covalent

Stronger metal atoms like 1st and 2nd group elements are bigger in size. Hence they are highly electropositive with low ionization potentials and tend to lose electrons easily and thus by forming big sized cations. According to Fajan’s rules, nature of bonds formed by larger cations is predominantly ionic since they have less polarizing power.
