Electrovalent Bonding (Ionic)

Topic Content:

The main principle of this type of bonding is donor/acceptor principle.

Electrovalent bonding is the complete transfer of electrons from the outermost shell of a metal to the outer-most shell of a non-metal.

The metals donate electrons while non-metals accept electrons. After combination, both the metal and non-metal will form a stable structure i.e. attain the octet or duplet structure of rare gases.

The metals are positively charged, while the non-metals are negatively charged.

Example:

Formation of Sodium chloride (Na⁺ Cl^– ):
