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 of a given elementare identical to each other 3. the atoms of different elements are different from … See more 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 See more Niels Bohr improved Rutherford’s model. Using mathematical ideas, he showed that electrons occupy shells or energy levels around the nucleus. See more 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 … See more
