| 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 sharetheir 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 sharingof 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. |
