$Na^{+}$

Vedclass · Answer

(A) All the given ions ($Na^{+}$,$Mg^{2+}$,$Al^{3+}$,$Si^{4+}$) are isoelectronic species,meaning they all have the same number of electrons ($10$ electrons).For isoelectronic species,the ionic radius decreases as the nuclear charge (atomic number) increases.Since $Na^{+}$ has the lowest atomic number $(Z = 11)$ among the given ions,it experiences the least effective nuclear attraction on its electrons.Therefore,$Na^{+}$ has the largest ionic radius.

Which ion has the largest radius from the following ions?

Which of the following atoms has the smallest atomic size?

Assertion : Atomic radius of gallium is higher than that of aluminium.
Reason : The presence of additional $d$-electrons offers poor screening effect for the outer electrons from increased nuclear charge.
