1.	With which of the following electronic configuration an atom has the lowest ionisation enthalpy? (a) 1s2 2s2 2p3 (b) 1s2 2s2 2p5 3s1 (c) 1s2 2s2 2p6 (d) 1s2 2s2 2p5
Answer» The correct option is: (b) 1s² 2s²2p⁵3s¹ Explanation: The larger the atomic size, smaller is the value of the ionisation enthalpy. Again higher the screening effect, lesser is the value of ionisation potential. Hence option (b) has lowest ionisation enthalpy.

Answer»

The correct option is: (b) 1s² 2s²2p⁵3s¹

Explanation:

The larger the atomic size, smaller is the value of the ionisation enthalpy. Again higher the screening effect, lesser is the value of ionisation potential. Hence option (b) has lowest ionisation enthalpy.
