WebAug 25, 2024 · Atomic Radius Trend 2: Atomic Radii Increase as You Move Down a Group The second atomic radius periodic trend is that atomic radii increase as you move downwards in a group in the periodic table. For each group you move down, the atom gets an additional electron shell. How are atomic radii related to the periodic table? Atomic Radii. WebWhen we move down a group in the periodic table, more energy levels are added, and so valence electrons would become further and further away from the positive nucleus. This causes the attraction between valence electrons and the nucleus to decrease, something known as the shielding effect.
