Scene 2 (18s)
[Audio] The Periodic Table displays a clear trend with atomic radius; as you move from left to right across each period, the atomic radius decreases, and if you move down a group, the atomic radius increases. This is due to the influence of two factors: the attraction force between electrons, which decreases from left to right, and the energy level of the elements, which increases from top to bottom. This is the cause of the inverse relationship between the attraction force and atomic radius, and the direct relationship between the energy level and atomic radius..
