Answer & Solution
Correct Answer
(D) Zn, Cd, Hg
Step-by-step Solution
Detailed explanation
\(\mathrm{Zn}, \mathrm{Cd}, \mathrm{Hg}:(\mathrm{n}-1) \mathrm{d}^{10} \mathrm{~ns}^2\) \(\therefore \quad \mathrm{Zn}^{2+}, \mathrm{Cd}^{2+}, \mathrm{Hg}^{2+}:(\mathrm{n}-1) \mathrm{d}^{10} \mathrm{~ns}^{\circ}\)
