- B \(\mathrm{Ca}^{2+}, \mathrm{Cl}^{-}, \mathrm{Al}^{3+}, \mathrm{O}_2^{-}\)
- C \(\mathrm{N}^{3-}, \mathrm{Mg}^{2+}, \mathrm{F}^{-}, \mathrm{O}^{2-}\)
- D \(\mathrm{Mg}^{2+}, \mathrm{O}_2^{-}, \mathrm{Cl}^{-}, \mathrm{N}_3^{-}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{N}^{3-}, \mathrm{Mg}^{2+}, \mathrm{F}^{-}, \mathrm{O}^{2-}\)
Step-by-step Solution
Detailed explanation
Iso-electronic species Atoms, molecules and ions that have the same electronic configuration are said to be iso-electronic. So, Number of electrons (a)\(\begin{array}{ll}\mathrm{N}^{3-} & =10 \\\mathrm{~F}^{-} & =10 \\\mathrm{O}_2 & =16 \\\mathrm{Ca}^{2+} & =10\end{array}\)…
