Covalent Bonds Ionic Bonds
Polarity Low High
Formation 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. 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.

What is it? Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds. Ionic bond, also known as electrovalent bond is a type of bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound. These kinds of bonds occur mainly between a metallic and a non metallic atom.
Melting point low High
Examples Methane (CH4), Hydro Chloric acid (HCl) Sodium chloride (NaCl), Sulphuric Acid (H2SO4 )
Occurs between Two non-metals One metal and one non-metal
Boiling point Low High
State at room temperature Liquid or gaseous Solid.
- 1. Lonic compounds are formed by the transfer of electrons that are positively and negatively charged, whereas, covalent compounds are formed by sharing the electrons.
- 2. In an ionic compound, bonding involves a metal and nonmetal, whereas, in the covalent compound, bonding is between nonmetals.
- 3 Lonic compounds are more soluble in water than covalent compounds.
- 4 Lonic compounds have definite shape whereas, covalent has no shape.
- 5 Lonic compounds are the good conductor of electricity, whereas covalent compounds are the bad conductor of electricity.
