 * 1) History of the Atom (5pts)
 * Find out the important scientists who contributed to our current knowledge of the atom. Include:
 * A picture.
 * When they lived.
 * What they did.
 * Find out the important experiments that were used to make breakthrough discoveries.
 * Who perfomed these experiments?
 * Include years of each discovery/experiment so we can get an idea of how long this process has taken.
 * 1) Atomic Structure (5pts)
 * What are the different parts of the atom?
 * What are the different particles that make up the atom?
 * Where are they located?
 * What makes atoms of different elements different?

JOHN DALTON: Born: September 6th, 1766. Died: July 27th, 1844. He created the Atomic Theory in chemisrty. He created this theory by having a fascination of whether in the atmosphere which his reasearch led to his nature of gasses.

J.J. THOMSON: Born: December 18th, 1856. Died: August 30th, 1940. He was awarded the Nobel Prize in Physics for the discovery of the electron and for his work on the conduction of electricty in gases. Thomson constructed a Crookes Tube. with an electrometer set to one side, out of the direct path of the cathode rays. Thomson could trace the path of the ray by observing the phosphorescent patch it created where it hit the surface of the tube. Thomson observed that the electrometer registered a charge only when he deflected the cathode ray to it with a magnet. He concluded that the negative charge and the rays were one and the same.
