Moseley’s Law Explained with Animation | Atomic Number, X-rays & Periodic Table Fix

Step into the world of early 20th-century physics and discover how Henry Moseley’s groundbreaking experiment reshaped our understanding of the periodic table. Through clear animations and realistic visuals, this video covers:

Moseley’s X-ray experiment setup

How electrons striking atoms produce characteristic X-rays

The √frequency vs. atomic number relationship

Why atomic number (Z) is more fundamental than atomic mass

The difference between proton number and nucleon number

How Moseley’s work corrected the periodic table

Perfect for high school and undergraduate physics or chemistry students.
