Question

Which is the correct statement regarding halogens?

(a) They are not all diatomic and form univalent ions

(b) They are all diatomic and do not form univalent ions

(c) They are all diatomic and form univalent ions

(d) They are all diatomic and form bivalent ions

The question was posed to me in unit test.

Question is from P-Block Elements topic in section P-Block Elements of Chemistry – Class 12

Answer 1

Correct choice is (c) They are all diatomic and form univalent ions

To explain I would say: Halogens are all diatomic and form univalent ions. All halogens can act as both oxidizing and reducing agents and are capable of exhibiting more than one stable oxidation state except Fluorine. Hence, option c is the correct statement.
