The element that shows greater ability to form multiple bonds, is :
Bonding Behaviour of P-block Elements -
Most of them are non-metal and form both covalent and ionic bonds.Most of the non-metals have polyatomic molecules.
carbon has the most tendency to form P(pie)-P(pie) multiple bonding.
As we have learned is chemical bonding. We know that carbon atom have 2p orbital and it is able to form strongest bond
