The atomic radii of the elements gradually decrease across the period from left to right. This is explained by the increase in the nuclear charge across the period due to an increase in the number of protons. Although there is an additional number of electrons, they enter the same energy level. This means that the shielding effect remains the same as the nuclear charge increases. The forces of attraction between the nuclei of these elements and the electrons in the outermost energy levels progressively increase across the period. As a result, the electrons in the outermost energy level are pulled closer to the nucleus, thereby decreasing the size of the atoms across the period from sodium to chlorine.

The atomic and ionic radii of the halogens increase down the group. This is because of the increase in the number of occupied energy levels. The atomic radius of a halogen atom is less than the radius of its ion. For example, the atomic radius of a chlorine atom is less than the ionic radius of a chloride ion. This is because the chlorine atom has 17 protons in the nucleus attracting 17 electrons in the energy levels. The chloride ion has 17 protons in the nucleus attracting 18 electrons. The effect of the positive nucleus is thus lower. The reduction in the nuclear attraction is due to repulsive effect between the existing electrons and the incoming electron.
