Answer:
The size of oxygen atom is quite
small. The oxygen atoms can be linked to each other by double bond \[(O=O)\]
because\[p\pi -p\pi \]bonding is possible in this case. Therefore, oxygen
exists in the gaseous state as discrete molecules. Multiple bonding is not so
effective in sulphur atoms due to large atomic size. Therefore, sulphur atoms
cannot be linked to each other by double bonds. In order to complete its octet,
each sulphur atom is linked with two sulphur atoms on tooth sides resulting in
a puckered ring \[({{S}_{8}})\]. Molecular sulphur\[({{s}_{8}})\] is a solid
since the van der Waal's forces of attraction are strong in the molecules.
