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 the reason is the correct explanation of the assertion

B

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

C

If assertion is true but reason is false

D

If the assertion and reason both are false

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 shell. I.E. is in given order.
