Question

Atomic radius goes on increasing down a group.​

Answer 1

Answer:

The atomic radius goes on increasing down a group, as atomic size increases down the group. This is because new shells are being added as we go down the group. This increases the distance between the outermost electrons and the nucleus so that the atomic size increases in spite of the increase in nuclear charge.

Answer 2

Atomic radius increases as we move from top to bottom in a group of the periodic table because a new shellof electrons are added to the atoms at every step. As the number of shells in the atoms increases gradually due to which thesize of atoms also increases.
