Question

Assertion: The metallic character increases as we go down the group.

Reason: Increase in size decreases the ionisation energy.

• A. Both assertion and reason are true and the reason is the correct explanation for the assertion.
• B. Both assertion and reason are true but the reason is not the correct explanation for the assertion.
• C. The assertion is true but the reason is false.
• D. The assertion is false but the reason is true.

Answer 1

The correct option is A

Both assertion and reason are true and the reason is the correct explanation for the assertion.

The metallic character increases as we go down the group since the size of atoms increases which results in the decrease of ionisation energy. So it is easy for an element with low ionisation energy to lose or donate electrons.
