GCSE Physics - Development of the model of the atom #31

The video explores the evolution of atomic theory, starting with Democritus' idea of indivisible particles. John Dalton later described atoms as solid spheres, leading to JJ Thompson's plum pudding model, which introduced electrons. Rutherford's gold foil experiment revealed a dense nucleus, forming the nuclear model. Niels Bohr refined this with his planetary model, explaining electron orbits. Further discoveries identified protons and neutrons, shaping our current understanding of atomic structure.
