Vedclass · Answer

(B) Fluorine $(F)$ is the most electronegative element in the periodic table.It has a small atomic size and lacks $d$-orbitals in its valence shell.Due to its high electronegativity,it can only gain one electron to complete its octet and cannot exhibit positive oxidation states or expand its octet.Therefore,it always exhibits an oxidation state of $-1$ in all its compounds.

Which of the following halogens does always show an oxidation state of $-1$?
