Describe the physical properties of the elements of Group $16$.
(N/A) Among the elements of Group $16$,oxygen and sulfur are non-metals,selenium and tellurium are metalloids,while polonium is a metal.
Polonium is radioactive and has a short half-life $(13.8 \ days)$. All these elements exhibit allotropy.
As we move down the group,the melting and boiling points increase with an increase in atomic number.
The large difference between the melting and boiling points of oxygen and sulfur can be explained based on their atomicity.
Oxygen exists as a diatomic molecule $(O_2)$,whereas sulfur exists as a polyatomic molecule $(S_8)$.
