Among the following transition elements, pick out the element(s) with the highest second ionisation energy
(i) V (Z = 23)
(ii) Cr (Z = 24)
(iii) Mn (Z = 25)
(iv) Cu (Z = 29)

A

(i)

B

(ii)

C

(iii)

D

(iv)

Text Solution

Verified by Experts

The correct Answer is:
D
`Cu^(+)` has a more stable configuration, `[Ar]3d^(10)`.
`IE_(II)=1962kJm^(-1)`
`Cr^(+)` has a stable configuration, `[Ar]3d^(5)`.
`IE_(II)=1635kJm^(-1)`
`3d^(10)` is more stable than `3d^(5)`.
