Correct order of first IP among following elements Be, B, C, N, O is
Options
(a) B< Be < C
Correct Answer:
B< Be < C Be – 1s²2s²; B – 1s²2s²2p¹; C – 1s²2s²2p²;N – 1s²2s²2p³;O – 1s²2s²2p⁴. IP increases along the period. But IP of Be > B. Further IP of O < N because atoms with fully or partly filled orbitals are most stable and hence have high ionisation energy. 18000+ students are using NEETLab to improve their score. What about you?
