This assumption persisted until experiments in physics showed that the atom … WebOct 13, 2016 · Rutherford’s discovery of the nucleus meant the atomic model needed a rethink. He proposed a model where the electrons orbit the positively charged nucleus. While this was an improvement on Thomson’s model, it didn’t explain what kept the electrons orbiting instead of simply spiralling into the nucleus. Enter Niels Bohr.
