Question

Assertion (A): Sulphur is an octatomic molecule.

Reason (R): The number of atoms in a molecule of an element is known as atomicity.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true but R is not the correct explanation of A.

Explanation:

Sulphur exists as S₈ molecules, so it is octatomic, and R correctly defines atomicity. The definition is true but does not by itself explain why a sulphur molecule contains eight atoms.
