The attractive force which holds together the atoms or group of atoms in a chemical species is known as a chemical bond. The definition of the chemical bond as a shared electron pair could be extended to describe the dative bond and the elaboration of Lewis acid/base interactions.
The ionic bond is the electrostatic force of attraction between two oppositely charged ions. Ionic bonds join metals to non-metals.
The covalent bond is also called a shared bond. These bonds join non-metals to non-metals.
What are Metallic bonds?
Metallic bonds are the chemical bonds that join metals to metals.
Difference Between Ionic bond, Covalent bond, and Metallic bond
To make you understand how Ionic, covalent and metallic bonds are different from each other, here are some of the major differences between Ionic, covalent and metallic bonds:
|IONIC BOND||COVALENT BOND||METALLIC BOND|
|Occurs during the transfer of electrons||Occurs when 2 atoms share their valence electrons||The attraction of metal cations/atoms and delocalized electrons|
|Binding energy is higher than the metallic bond||Binding energy is higher than the 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|
|Higher boiling point||Lower boiling point||High boiling point|
These were some important differences between Ionic, covalent and metallic bonds.
