Covalent bonding

IB Chemistry: Covalent bonding

The IB uses Pauling’s scale of electronegativity. It was Linus Pauling who first proposed the idea that the bonding electrons pair between two different atoms is not shared equally. If the electrons are in the same outer electron energy level in both atoms then they will tend to be closer to the atom with the greater number of protons in the nucleus resulting in a polar bond. Similarly the closer the outer electron...
