Vedclass · Answer

(B) Statement $(i)$ is incorrect: The atomic radius of $Al$ $(143 \ pm)$ is actually larger than that of $Ga$ $(135 \ pm)$ due to the poor shielding effect of $d$-electrons in $Ga$.Statement $(ii)$ is correct: Boron exists in several allotropic forms such as $\alpha$-rhombohedral, $\beta$-rhombohedral, and $\beta$-tetragonal.Statement $(iii)$ is correct: The melting point of $Ga$ $(303 \ K)$ is the lowest among group $13$ elements due to its unique crystal structure.Therefore, statements $(ii)$ and $(iii)$ are correct.

Identify the correct statements from the following:
$(i)$ The atomic radius of $Al$ is lower than the atomic radius of $Ga$.
$(ii)$ Boron exists in many allotropic forms.
$(iii)$ The melting point of $Ga$ is lowest among the group $13$ elements.
