GCSE Chemistry - History of the Model of the Atom #7

The video explores the evolution of atomic theory, starting with Democritus' idea of indivisible particles. John Dalton later described atoms as solid spheres, followed by JJ Thompson's plum pudding model introducing electrons. Rutherford's gold foil experiment led to the nuclear model, identifying a dense nucleus. Niels Bohr refined this with his planetary model, explaining electron orbits. Further discoveries identified protons and neutrons, forming the modern atomic model.
