Anomalous behaviour of oxygen????​

Answer»
Anomalous behaviour of OXYGEN

Oxygen forms strong HYDROGEN bonding in H2O which is not found in H2S. Also, the maximum covalency of oxygen is four, whereas in a CASE of other elements of the group, the valence shells can be expanded and covalency EXCEEDS four.
