Question

The element with the smallest size in group 13 is ___.

Answer 1

The distance between the centre of the nucleus and the outermost shell of an atom is known as the atomic radius. In a group, the atomic radius increases due to the addition of new filled shells as we move from one period to another. The element with the smallest size in group 13 is Boron. Boron is a non-metallic element and the only non-metal of the group 13 of the periodic table.
