Q. For the second period elements the correct increasing order of first ionisation enthalpy is

NEETNEET 2019Classification of Elements and Periodicity in Properties

Solution:

‘Be’ and ‘N’ have comparatively more stable valence sub-shell than ‘B’ and ‘O’.
$\therefore $ Correct order of first ionisation enthalpy is:
Li < B < Be < C < O < N < F < Ne
