2. What causes this trend? Energy levels are added as you go down the periodic . table, these energy levels are further away from the nucleus, thus increasing the atomic radius. 3. What trend in atomic radius do you see as you go across a period/row on the periodic table? The atoms radius decreases. 4. What causes this trend?
