| સૂચિ $I$ | સૂચિ $II$ |
|
$A.$ $M$ $P$ $[\mathrm{K}]$ |
$I.$ $\mathrm{Tl}>\mathrm{In}>\mathrm{Ga}>\mathrm{Al} > \mathrm{B}$ |
|
$B.$ આયનિક ત્રિજ્યા $\left[\mathrm{M}^{+3} / \mathrm{pm}\right]$ |

(JEE MAIN-2024)
Solution
Melting point : $\mathrm{B}>\mathrm{A} \ell>\mathrm{T} \ell>\mathrm{In}>\mathrm{Ga}$
Ionic radius $\left(\mathrm{M}^{+3} / \mathrm{pm}\right): \mathrm{T} \ell>\mathrm{In}>\mathrm{Ga}>\mathrm{A} \ell>\mathrm{B}$
$\left(\Delta_{\mathrm{IE}} \mathrm{H}\right)_1\left[\frac{\mathrm{kJ}}{\mathrm{mol}}\right]: \mathrm{B}>\mathrm{T} \ell>\mathrm{A} \ell \approx \mathrm{Ga}>\mathrm{In}$
Atomic radius (in $\mathrm{pm}$ ) : $\mathrm{T} \ell>\mathrm{In}>\mathrm{A} \ell>\mathrm{Ga}>\mathrm{B}$
