The original 'Bohr' model of the atom consisted of a nucleus of protons and neutrons with electrons orbiting about it.
It actually hasn't changed very much in the last hundred years, except for our better understanding of electron orbitals, spin states, and energy levels.

The "plum pudding" model described the atom as electrons suspended in a positively charged substance
The Bohr model described the atom with a central, positively charged nucleus with electrons orbiting the atom in quantized energy levels, where the electrons can "jump" between energy levels by gaining or losing specific amounts of energy
In the quantum mechanical model, there are no fixed "orbits" for electrons, and the position of an electron is described in terms of probability. Electrons themselves are thought of as waves rather than particles. The more you know about the position of an electron at any moment, the less you can know about its velocity.

Well lets see there's the original one ball is all an atom consists of, the plum pudding model (ie a cloud with negative charges throughout), then the bohr model with the electron orbits around the nucleus, and now there is a nucleus surrounded by a cloud of electrons... but i feel like i'm missing one because i took chemistry last year. It's best just to go to wikipedia.
