Assertion: Ionisation potential across t...

Assertion: Ionisation potential across the period is `NaltAlltMgltSi`.
Reason : Ionisation potential decreases with decrease in atomic size.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If the assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Assertion is true but reason is false.
Ionisation potential decreases with increase in atomic size and also for a given a shell. I.E. Is in given order.
