WebThe 19th and early 20th centuries saw great advances in our understanding of the atom. This module takes readers through experiments with cathode ray tubes that led to the discovery of the first subatomic particle: the electron. The module then describes Thomson’s plum pudding model of the atom along with Rutherford’s gold foil experiment that … WebThe Geiger–Marsden experiments (also called the Rutherford gold foil experiment) ... Accelerating charged particles radiate electromagnetic waves, so an electron orbiting an atomic nucleus in theory would spiral into the nucleus as it loses energy. Obviously this wasn't happening. The answer to this paradox came via quantum mechanics. the viper\u0027s drag https://prideprinting.net
