Aristotle (340 BC)
He descovered that atoms are elements of matter. He used Democritis' atomic theory to discover this. "Aristotle." N.p., n.d. Web. http://the-history-of-the-atom.wikispaces.com/Aristotle. -

Dalton (1800 AD)
He discovered that elements consisted of tiny particles; and the law of composition. He used other atomic theorys to discover this. "John Dalton's Atomic Theory." N.p., n.d. Web. 27 Feb. 2014. http://www.universetoday.com/38169/john-daltons-atomic-model/. -

Thomson (1897 AD)
He discovered isotopes and subatomic particles. He used the atomic theorys and electric and magnetic feilds. He thought the atom looked like two patches of light. "Thomson's Atomic Theory."

Rutherford (1912 AD)
He descovered that electrons where on the outside opf the atom.He used thomson's experiment and thought it looked like plum pudding. "Rutherford's Atomic Theory." N.p., n.d. Web. 27 Feb. 2014. http://www.iun.edu/~cpanhd/C101webnotes/modern-atomic-theory/rutherford-model.html. -

Bohr (1911 AD)
He descovered that electrons give off energy. He used Rutherford's experiment to discover this. He thought the atom looked unstable "Rutherford's Atomic Theory." N.p., n.d. Web. 27 Feb. 2014. http://www.iun.edu/~cpanhd/C101webnotes/modern-atomic-theory/rutherford-model.html. -
