Question

Give any three differences between ionic bonds and covalent bonds

Answer 1

Polarity of:
Covalent Bonds:Low
Ionic Bonds: High
Formation of:
Covalent bond:A covalent bond is formed between two non-metals that have similar electronegativities. Neither atom is "strong" enough to attract electrons from the other. For stabilization, they share their electrons from outer molecular orbit with others.
Ionic bond:An ionic bond is formed between a metal and a non-metal. Non-metals(-ve ion) are "stronger" than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond.
Melting point of:
Covalent bond:low
Ionic bond:high
