On this page we'll be comparing and contrasting the five models of the atoms discussed on this wikispace.
So...
How are they the same?
  1. All of them have no overall charge
  2. They're all generally circular
That is where the similarities end so now we get to look at how they're different.
How is Ernest Rutherford's model unique?
  1. He had electrons orbiting the nucleus randomly
  2. His model had empty space
How is J.J. Thomson's model unique?
  1. He had a positively charged jelly like substance
  2. His electrons were free-floating
How is John Dalton's model unique?
  1. His model was a solid ball
How is Niels Bohr's model unique?
  1. His model had the electrons orbiting the nucleus in circles but they were still random
How is Schrödinger's model unique?
  1. His has energy "shells"
  2. A set number of electrons are found in each shell
  3. His is probably correct
