Given below are the pairs of group 13 elements showing their relation in terms of atomic radius.
\((\mathrm{B}<\mathrm{Al}),(\mathrm{Al}<\mathrm{Ga}),(\mathrm{Ga}<\mathrm{In})\mathrm{and}(\mathrm{In}<\mathrm{Tl})\)
Identify the elements present in the incorrect pair and in that pair find out the element (X) that has higher ionic radius \(({\mathrm{M}}^{3+})\) that the other one. The atomic number of the element (X) is
