Periodic Trends: Atomic Radius (Chemistry Explained)

 

This video explains the periodic trend of atomic radius and why atomic size changes across the periodic table. You’ll learn how atomic radius varies across periods and down groups — and why those patterns exist. In this lesson, you’ll learn: • What atomic radius means • How atomic radius changes across a period • How atomic radius changes down a group • The role of nuclear charge and electron shielding • Common mistakes students make with periodic trends This explanation is great for: • High school chemistry • Intro / general chemistry • Periodic trends and atomic structure • Homework help and exam prep 👉 If periodic trends have ever felt like memorization, this explanation will help the pattern finally make sense.
