Sulphur does not exist as S2 molecule because
it is less electronegative
it is not able to constitute bonds
it has ability to exhibit catenation
of tendency to show variable oxidation states
B.
it is not able to constitute bonds
Sulphur does not form bond due to its larger size, hence does not exist as S2 molecules.
