🔬 Understanding Electron Shells

Diagram showing electron shell configurations for Carbon (2,4), Sodium (2,8,1) and Chlorine (2,8,7). Shows nucleus with protons and neutrons, electron shells with electrons, and key rules: 1st shell max 2 electrons, 2nd and 3rd shells max 8 electrons. Group number equals outer shell electrons.

💡 Key: Electron configuration determines how atoms form ions and bonds!
