WebB: Boron has the smallest atomic radius among group 13 elements. Ga: In Ga, the d orbital does not shield the nucleus effectively. So the effective nuclear charge is higher for the outermost electrons. So, the atomic radius is smaller. Al: Down the group, the effective nuclear charge decreases as the number of shells increases, So the atomic ...
