Web21 aug. 2024 · Atomic Radius (increases down the group) The size of the nucleus increases down a group ( F < Cl < Br < I < At) because the numbers of protons and neutrons increase. In addition, more energy levels are added with each period. This results in a larger orbital, and therefore a longer atomic radius. Ionization Energy (d ecreases down the group) WebFigure 8.2.6: Definition of Ionic Radius. (a) The internuclear distance is apportioned between adjacent cations (positively charged ions) and anions (negatively charged ions) in the ionic structure, as shown here for Na + and Cl − in sodium chloride.
