Concept introduction:
The electron dot formula shows the valence electrons which form the bond between the atoms in a molecule. The electron pairs that are shared by the atoms are known as bonding electrons. The other electrons that are present in order to complete the octet are known as non-bonding electrons. The electron dot formula is also known as the Lewis structure.
