How do You Think the radius of an atom will change as you move down a Group (Vertical Column) in the periodic table

As you move left to right, the atomic radius gets SMALLER, so atoms hold on to their electrons more tightly and are more reactive. As you move down a group, the atomic radius gets LARGER, so atoms have a weaker hold on their electrons and are less reactive
