Vedclass · Answer

(A) Halogens $(F_2, Cl_2, Br_2, I_2)$ are all diatomic molecules in their elemental state. They have a general valence shell configuration of $ns^2 np^5$,which allows them to gain one electron to form univalent halide ions $(X^-)$. While most halogens exhibit multiple oxidation states,the statement that they are all diatomic and form univalent ions is the most fundamental and universally correct characteristic among the given options.
