WebRutherford disproved Thomson’s model with his well-known gold foil experiment in 1911, demonstrating that the atom has a tiny and heavy nucleus. In addition, Rutherford devised an experiment in which alpha particles emitted by a radioactive element served as probes into the world of unseen atomic structure. Hans Geiger and Ernest Marsden tested the plum pudding model. They aimed beams of positively-charged particles at very thin gold foil. These particles should have passed straight through, according to the plum pudding model. However, many of them changed direction. Ernest Rutherford explained these results … Ver mais John Dalton thought that all matter was made of tiny particlescalled atoms, which he imagined as tiny solid balls. Dalton’s model included these ideas: 1. atoms cannot be broken down into anything simpler 2. the atoms … Ver mais J.J. Thomson discovered the electron. Atoms are neutral overall, so in Thomson’s ‘plum pudding model’: 1. atoms are spheres of positive charge 2. electrons are dotted around inside Ver mais Niels Bohr improved Rutherford’s model. Using mathematical ideas, he showed that electrons occupy shells or energy levels around the nucleus. Ver mais
