Write on the electropositivity of iodine.

Explanation

All halogens are non-metals. Iodine is also a nonmetal. However, iodine shows certain electrpositivity.
The` +1` state is more stable for iodine, as evidenced in molten ICl and molten ICN
Only iodine is naturally available in positive oxidation states. `NaIO_3` is its mineral.
lodine is the only halogen uses three d-orbitals for hybridisation, `sp^3 d^3` in `IF_7`.
