BRAINCAKEPolar Covalent Bonds
In a non-polar bond, the bonded electron pair is shared equally between the two bonded atoms because either the atoms have the same or similar electronegativities or the atoms are the same.
for instance in O2 or Cl2. In these cases the bond is a pure covalent bond.
Polar bonds are formed between atoms with different electronegativities.
