ATOMIC SIZE : Periodic Properties | Covalent Radius | Van Der Waals Radius | Metallic Radius | NEET

We start by defining what atomic radius is and the different ways it can be measured (like Covalent Radius, Metallic Radius, and Van der Waals Radius). The core of the video focuses on the two major atomic radius trends across the periodic table: ➡️ Across a Period (Left to Right): Learn why atomic radius decreases. We explore the concept of Effective Nuclear Charge (Z eff) and how increasing protons pull valence electrons closer, shrinking the atom! ⬇️ Down a Group (Top to Bottom): Discover why atomic radius increases. This is all about adding new energy shells (principal quantum numbers) and the role of electron shielding. By the end of this lesson, you'll be able to predict the relative size of any element based on its position on the periodic table. Perfect for high school and college students!
