Thomson made a model of the atom that suggested that negatively charged particles were embedded in a positively charged substance. The model became known as the plum pudding model because it looked like a big pudding with blobs in it. -
Rutherford begins experimenting with a new model of the atom which suggests that the atom has a nucleus. The nucleus is very dense and holds a positive charge -
This model shows a positively charged nucleus being orbited by small electrons. Bohr's model is similar to the way that planets orbits the sun -
Schrodinger used the Bohr atomic model and applied quantum mechanics to the idea. This model showed the likelihood of electrons being in certain locations at certain points in time. -
Today we know a lot more about the atom and we have much better technology so there isn't as much guesswork. Some scientists devote their whole careers to studying and experimenting with atoms.
