Step 1I'll solve this problem by explaining the key factors that cause atomic radius to increase when moving down a chemical family (group) in the periodic table.
Step 2: Understanding Atomic Radius
Atomic radius is the distance from the nucleus to the outermost electron shell. As you move down a chemical family, the atomic radius increases due to two primary factors:
Final Answer
1. Addition of new electron shells 2. Increased electron shielding effect 3. Reduced effective nuclear attraction to outer electrons
