The atomic numbers of vanadium (V), chromium (Cr), manganese (Mn) and iron (Fe) are respectively 23, 24, 25 and 26. Which one of these may be expected to have the highest second ionisation enthalpy ?
V
Cr
Mn
Fe

A

`Cr`

B

`Mn`

C

`Fe`

D

`V`

Text Solution

Verified by Experts

The correct Answer is:
1
`Cr^(+)` has stable half filled electronic configuration ,`[Ar]^(18)3d^(5)4s^(0)`. The removel of one more electron from this stable half filled confihuration will require higher energy.
