Vedclass · Answer

(B) $1$. For a given element,the ionic radius follows the order: $Anion > Neutral \ atom > Cation$. Thus,$I^{-} > I > I^{+}$ is correct.$2$. For isoelectronic species or ions of the same element,the radius decreases as the positive charge increases. $N^{3-}$ has a larger radius than $N^{5+}$ because $N^{3-}$ has more electrons and greater electron-electron repulsion,while $N^{5+}$ has fewer electrons and higher effective nuclear charge. Therefore,the order $N^{3-} $3$. Similarly,$P^{5+} $4$. Across a period from left to right,atomic radius decreases due to an increase in effective nuclear charge. Thus,$Li > Be > B$ is correct.$5$. The incorrect order is $N^{3-} < N^{5+}$.
