Question

The group having isoelectronic species is:

• A. $O^{-},F^{-},Na,M{g}^{+}$
• B. $O^{2-},F^{-},Na,M{g}^{2+}$
• C. $O^{-},F^{-},N{a}^{+},M{g}^{2+}$
• D. $O^{2-},F^{-},N{a}^{+},M{g}^{2+}$

Answer 1

The correct option is D $O^{2-},F^{-},N{a}^{+},M{g}^{2+}$

$O^{2-},F^{-},N{a}^{+}$ and $M{g}^{2+}$, all have 10 electrons each.
