Question

Which of the following statements about halogens is correct?

• A. They are all diatomic and form univalent anions
• B. They are all capable of exhibiting several oxidation states
• C. They are all diatomic and form divalent ions
• D. They can mutually displace each other from the solution of their compounds with metals

Answer 1

The correct option is A They are all diatomic and form univalent anions

Halogens are all diatomic and form univalent anions.

Except for Fluorine, all halogens are capable of exhibiting several oxidation states.

None of the halogens form divalent ions.

They can not mutually displace each other from the solution of their compounds with metals.

Hence, Option "A" is the correct answer.
