Electron Energy Levels and Valency

The video explains atomic structure, focusing on protons, electrons, and neutrons. It details electron shells and their role in stability, introduces valence electrons and their impact on reactivity, and shows how the periodic table helps determine valency. It concludes with a discussion on chemical bonds, including ionic and covalent bonds, and their properties.
