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.

Chloride ion $(Cl^-)$ and potassium ion $(K^+)$ are isoelectronic. Then:

The ionic radius of $Na^{+}$ ions is $1.02 \ \mathring{A}$. The ionic radii (in $\mathring{A}$) of $Mg^{2+}$ and $Al^{3+}$,respectively,are
