| Term | Definition |
|---|---|
| JJ Thompson | Cathode Ray Tube; Discovered and identified the mass to charge to ratio for electrons |
| Robert Millikan | Oil Drop Experiment; Discovered the charge of the electron |
| Ernest Rutherford | Characterized beta and alpha particles ; discovered the proton w/a mass spectrometer; discovered the nucleus w/the gold foil experiment; proposed the nuclear theory |
| Dalton's Atomic Theory 1 | Matter consists of tiny particles called atoms. |
| Dalton's Atomic Theory 2 | In a sample of a pure element, all atoms are identical & have the same properties. |
| Dalton's Atomic Theory 3 | Atoms of different elements differ in mass & other properties. |
| Dalton's Atomic Theory 4 | Compounds are formed when atoms of more than one element combine; a given compound always has the same relative number and kind of atoms |
| Dalton's Atomic Theory 5 | Atoms of an element are not changed into atoms of a different element by chemical reactions; atoms are neither created nor destroyed in chemical reactions. |
