MCQ
Which of the following element has maximum first ionisation potential
- A$V$
- B$Ti$
- C$Cr$
- ✓$Mn$
✓
Answer
Correct option: D.
$Mn$
d
(d)The first ionization energies of $Ti,\,V,\,Cr$ and $Mn$ are $656,\,650,\,652 $ and $717\,kJ/mole$ respectively.
(d)The first ionization energies of $Ti,\,V,\,Cr$ and $Mn$ are $656,\,650,\,652 $ and $717\,kJ/mole$ respectively.
I.E. increase in a period from $L \to R$
hence, manganese has maximum first ionisation potential.
