Tested Democritus’ idea 2000 years later 

Atomic Theory:

All matter is made up of atoms

Atoms are indivisible: cannot be broken down into smaller particles

All atoms of one element are exactly alike, but they are different from atoms of other elements 

A given compound always has the same relative numbers and kinds of atoms. Atoms join in whole number ratios

Atoms are neither created nor destroyed in any chemical reaction 

Believed atom was a solid sphere (marble-like)

Used Cathode Ray Tube experiment to prove the atom was made of electrons 

Could bend the light and particles traveled from negative to positive ends 

Discovered electron

Altered Dalton’s model of the atom because now there is something inside of it 

Knew that because there is a negative charge (electron) there must be something in it that gives off a positive charge because atoms are neutral

Plum Pudding model: atoms was made of positively charged stuff with negatively charged particles spread apart

Gold Foil Experiment: shot alpha particles (very small, fast, dense) at gold foil

Expected all particles to go through - some did, but other didn’t 

Came up with nucleus

Proved atom was mostly empty, but small, dense and positive nucleus is inside

Won a Nobel Prize for his work on the atom
