ANOMALOUS BEHAVIOUR OF OXYGEN - DEFINITION
The reasons are:
Small size
Higher electronegativity
Non-availabiity of d-orbitals
Oxygen is a gas while others are solids at room temperature. Oxygen is a non-metal. Sulphur is non-metallic while others exhibit metallic character. Due to small size and high E.N, oxygen form pπ−pπ multiple bonds with elements having similar size. Oxygen is paramagnetic while others are diamagnetic.
