Free PowerPoint on Atomic Structure | Models, Electron Configuration & Energy Levels
This PowerPoint explains atomic structure, covering historical atomic models from Democritus, Dalton, Thomson, Rutherford, and Bohr. It details protons, neutrons, and electrons, their charges, and mass, along with electron configurations, energy levels, and dot-and-cross diagrams. The gold foil experiment and plum pudding model are highlighted, demonstrating how atomic theory evolved. A useful resource for students learning about atomic properties, configurations, and periodic trends.
