Difference Between Ionic, Covalent and Metallic bonds

Chemistry is a subject to explore the chemical structure, properties, bonds of substance etc. There are three types of chemical bonds that we will be discussing here. They are Ionic bond, covalent bond and metallic bond.

Ionic bond:

Ionic bonds join metals to nonmetals.

Covalent bond:

Covalent bond is also called as sharing bond. These bonds join nonmetals to nonmetals.

Metallic bonds:

Metallic bonds are the chemical bonds that join metals to metals.

To make you understand how Ionic, covalent and metallic bonds are different from each other, here are the some of the major differences between Ionic, covalent and metallic bonds:


Occurs during transfer of electrons

Occurs when 2 atoms share their valence electrons

Attraction of metal cations/atoms and delocalised electrons

Binding energy is higher than metallic bond

Binding energy is higher than metallic bond

Binding energy is less than covalent and ionic bond

Low conductivity

Very low conductivity

Has high electrical conductivity

Non directional bond

Directional bond

Non directional bond

Present only in one state : solid state

Present only in all 3 states: solid, liquid, gases

Present only in one state : solid state




Higher melting point

Lower melting point

High melting point

Non ductile

Non ductile


Higher boiling point

Lower boiling point

High boiling point

These were some of the important difference between Ionic, covalent and metallic bonds.
