Atomic radius is defined as the distance from the outermost ring‚ referred to the valence shell‚ to the centre of the atom. On the periodic table‚ going across from left to right‚ the atom’s relative size decreases. However‚ going down the group‚ the atomic radius increases in size. From left to right there is an increase of positive charges in the neutron and the electrons. Due to the increase of the number of positive charges‚ the electron’s attractive force becomes stronger‚ thus (the electrons)
