InterviewSolution

1.	`Zn^(+2)` ion is isoelectronic withA. `Fe^(+2)`B. `Cu^+`C. both a and bD. `Ni^(+2)`
Answer» Correct Answer - B `Zn^(+2)` ion is isoelectronic with `Cu^(+1)` as both have same number of `e^-` and hence same configuration `Zn^(2+) - 1s^2 2s^2 3s^2 3p^6 4s^0 3d^10` `Cu^(+) - 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^0` `therefore ` isoelectronic
