These were the people that came up with the theory of matter being made out of tiny particles.
-
At first they thought that if cut something in half so many time, you'll reach a particle that can't be cut anymore
-
Proposed the law of conservation
-
Determined that elements exist as discrete packets of matter
-
These are gas-filled tubes with electrodes at each end which emits light
-
Found that the tubes also emits light with positive electrodes
-
Took the tube research further; He was able to measure the mass rays; He concluded that the rays weren't rays or waves they were very small and light negative particles. (Pretty much created electrons)
-
Proposes that electrons weren't particles or waves instead they had properties of both and neither
-
Designed an experiment using an extremely thin sheet of gold foil and screen created with zinc; concluded that most of an atom is just empty space.
-
Discovered that its impossible to know with certainty the momentum of an electron or any subatomic particles
