The explanation for why Sulfur has a smaller atomic radius than Silicon.
Sulfur has more protons than Silicon, creating a higher effective nuclear charge (Zeff). This stronger positive charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
Bonus: The atomic radius gets ___ going across the period, and ___ going down the family.
