1.	Which statement is correct about halogens ?A. They are all diatomic and form univalent ionsB. They are all capable of exhibiting several oxidation statesC. They are all diatomic and form divalent ionsD. They can mutually displace each other from the solution of their compounds with metals.
Answer» Correct Answer - A All halogens are diatomic (e.g., `F_2, Cl_2, Br_2, and I_2)` and all of them form univalent ions `(F^(-), Cl^(-), Br^(-) and I^(-))`.
