As atomic number increases within Group 15 on the Periodic Table, atomic radius
(1) decreases, only
(2) increases, only
(3) decreases, then increases
(4) increases, then decreases

Answer is: (2) increases, only.

The atomic radius of a chemical element is a measure of the size of its atom.

The atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

Nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi) and moscovium (Mc) are in group 15 of Periodic table. They have same number of valence electrons (five).

Nitrogen has smallest atomic number and smallest atomic radius.

As atomic number increases within group 15, the atomic radius ; ( 2 )

  • Increases only

In the periodic table, the size of the atomic radius will continue to change as the the atomic number of the elements increase. Elements in the same group have the same/similar number of valence electron counts and also similar vacancy counts as well.

Therefore as  you go down the group, the atomic number of the elements in the same group increases and in response to that the distance between the nucleus and the outermost shell will also increase ( which is the atomic radius ).

Hence we can conclude that As atomic number increases within group 15,the atomic radius  Increases only .
