$Zn$

Vedclass · Answer

(B) The correct answer is $(B)$ $Zn$. The electronic configuration of $Zn$ is $[Ar] 3d^{10} 4s^2$. The first ionisation potential removes one $4s$ electron,leaving $[Ar] 3d^{10} 4s^1$. The second ionisation potential involves removing the remaining $4s$ electron. Since the $3d^{10}$ subshell is completely filled,it provides a strong shielding effect,which reduces the effective nuclear charge felt by the $4s$ electron,making it easier to remove than expected compared to other transition metals.

Which of the following has second ionisation potential less than expected?
