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.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
In a period from left to right, effective nuclear charge increases and size decreases, as a result ionisation energy increases. But elements of II A and V A group on the account of their half - filled and completely filled orbitals have high IE than the elements of III A and VI A group, respectively.
