  -1st person to incestigate dbasic principles of atoms

  -"Cutting The Cheese" (mental experiment)
-Cut an object until it couldn't get any smaller, the smallest would be an atom - 
  
  -Didn't believe in atomic theory
-Believed in earth, wind, fire, water element - 
  
  -Contribuuted to the idea that atoms are held together by attractions or forces.

  -Atomic Theory Experiment
1. All matter is made up of tiny particles called atoms
2. All atoms of a given element are alike, but are different from the atoms of any other element
3. Compounds are formed when atoms of different elements combine in fixed proportions
4. A chemical reaction involves a rearrangment of atoms, hot a change in the atoms themselves. -
