How would you account for the irregular of ionisation enthalpies (first) in the first series of the transition elements?

Text Solution

Verified by Experts

Irregular variation of ionisation enthalpies is mainly attributed to varying degree of stability of different 3d-configuration (e.g., `d^(0),d^(5),d^(10)` are exceptionally stable.)
