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

A

(a)`Mn`

B

(b)`Fe`

C

(c )`V`

D

(d)`Cr`

Text Solution

Verified by Experts

The correct Answer is:

D

`Cr` has `3d^(5), 4s^(1)` configuration and thus second electron is removed from 3d-subshell. Rest all from 4s-subshell.
