For example, H and Li (in group 1A) both have 1 valence e-, but H’s is in the first energy level, and Li’s is in the 2nd. This trend continues down each family/group. 3. What trend in atomic radius do you see as you go across a period/row on the periodic table? Across (LR) a period, atomic radius decreases. 4. What causes this trend?
