Aristotle (2500 years ago/4th or 5th B.C.)
He didn't believe atoms could be constantly moving if they were in a void, he believed that everything was made of fire, air, water, and earth. "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. N.p., n.d. Web. 25 Feb. 2014. -

Democritus (2500 years ago/4th or 5th B.C.)
He cut a peice of bread in half and then he took that and cut it, eventually you come to a point to where you can't cut it anymore. atomos="uncuttable" and that is how they got the word atoms.

He found out they had electrons.The atoms have smaller things. He also saw electrons in the dough in the atom like the blueberries in the dough.

Rutherford (1911)
Before, they called the atom the Plum Pudding Atom. Atoms were empty spaced called the nuclear model. "GaggleTube Video - Discovery of the Nucleus: Rutherford's Gold Foil Experiment." GaggleTube Video - Discovery of the Nucleus: Rutherford's Gold Foil Experiment. N.p., n.d. Web. 27 Feb. 2014. -
Bohr (1913)
He had no ideas just like Rutherford but instead of the electrons being anywhere they would orbit. "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. N.p., n.d. Web. 25 Feb. 2014. -
Heisenburg and Schrodinger(1920)
They were buzzing around making different shapes. They didn't really orbit. It would make a certain line. "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. N.p., n.d. Web. 25 Feb. 2014.
