Question

Which of of the following are isoelectronic species. Al³+, Mg 2+ , Cl, Na+, k+, 0², N³ comments​

Answer 1

Answer:

$Al^{3+},Mg^{2+},Na^{+}$$,O^{2-},N^{3-}$

Explanation:

Isoelectronic species are known as atoms or ions that have the same number of electrons

electrons in:

$Al^{3+} = 10$

$Mg^{2+} = 10$

$Cl = 17$

$Na^{+} = 10$

$K^{+} = 18$

$O^{2-} = 10$

$N^{3-} = 10$

∴ The isoelectronic species are $Al^{3+},Mg^{2+},Na^{+}$$O^{2-},N^{3-}$.
