E Gided practice 3L Why does the atomic radius get smaller as you go toward the right side of the penodic table? As you move to the right on the penodic table, the number of protons in the nucleus increases, which makes the nucleus O A more attracted to the electrons and pulls the rings inward making the radius of the atom smaller. As you move to the right on the periodic table the atoms become older and begin to shrink. This causes the overall radius of the atom to be smaller on the left side of the periodic table. Because the number valence electrons increases as you move to the right on the perioic table, the valence shell becomes more creowded and causes the atomic radius to be smaller on the left side of the table. Although the atomic mass increases as you move to the right side of the…
