Question
Which of the following element has maximum, first ionisation potential
✓
Answer
d
The first ionization energies of $Ti , V , Cr$ and $Mn$ are $656,650,652$ and $717\, kJ / mol$ respectively. Ionisation energy increase gradually but not strictly in a period from $L \rightarrow R$ hence, manganese has maximum first ionisation potential.
