Q: How does atomic radius change down a group?
Atomic radius refers to the distance between the nucleus of an atom and the outermost electron. It is a fundamental property that affects an element's chemical reactivity, physical properties, and behavior. As you move across a period (left to right) in the periodic table, atomic radius generally decreases due to the increasing number of protons in the nucleus, which pulls electrons closer to the center. Conversely, as you move down a group (top to bottom), atomic radius increases due to the addition of energy levels, which results in a greater distance between the nucleus and the outermost electron.
