The p-Block Elements
Give Reason:
Dioxygen is a gas while Sulphur is a solid at room temperature.
Oxygen is smaller in size and thus due to its small size complete its octet by forming pπ = p bond. Therefore, O2 is a discrte molecule and the intermolecular forces of attraction are weak vander waals forces. Hence, O2 is a gas. While sulphur is large in size, cannot form p= p bonds. Therefore, in order to gain stability, it exists as S8 which is a solid.
