313304 Assertion :
First ionisation energy for nitrogen is lower than that of oxygen
Reason :
Across a period, effective nuclear charge decreases.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
