Chapter 2: Q10P (page 40)

Is $S^{2 -}$ larger or smaller than ${Cl}^{-}$ ? Is ${Mg}^{2 +}$ larger or smaller than ${Na}^{+}$ ? Explain.

Short Answer

Expert verified

$S^{2 -}$ is larger than ${Cl}^{-}$ .

${Mg}^{2 +}$ is smaller than ${Na}^{+}$ .

Step by step solution

Isoelectronic ions

These are chemical species in which any two atoms or molecules or ions have the same number of valence electrons or the same electronic configuration.

Explanation

Among $S^{2 -}$ and ${Cl}^{-}$ , both are isoelectronic ions. For isoelectronic anion, size increases as the charge on the ion increases. Hence, the charge on sulfur is more compared to chloride ions. Thus, $S^{2 -}$ is larger than ${Cl}^{-}$ .

Among and , both are isoelectronic with 10 electrons and are isoelectronic cations. For isoelectronic cation as the charge of the cation increases, size decreases. Hence, the charge on magnesium is more compared to sodium. Thus, is smaller than .
