what happens to the radius of the atoms of an element as you go towards the right in a row of the periodic table ?

Olegator [25]

Answer:

It decreases

Explanation:

As one moves from left to right on the periodic table, the radius of atoms reduces due to the nuclear pull.

The size of an atom estimated by the atomic radius is taken as half of the internuclear distance between the two covalently bonded atoms of non-metallic elements.
Across a period, atomic radius decreases progressively from left to right.
This is due to the increasing nuclear charge without attendant increase in the number of electronic shell.
