He believed in "Atomos". This means that everything is split up into half and eventually it has to end with an atom.
-
He believed that everything was made of fire.
-
He believed that everything was made from four elements. Earth, Fire, Earth, and water.
-
- All matter is composed of small particles
- All atoms of elements are identical in sizes
- Atoms cant be subdivided
- Atoms have to have whole number ratios
- Chemical reactions change the bonds
-
A cathode ray adds voltages through two separate tubes and whenever they interact it lights up.
-
When he put in two positive charges the light till went off. They should have repelled each other, but the light still went off. This is showing that there was a negative charge involved. Thus, an atom does have more parts then we believed.

-
He discovered the nucleus.
-
He found out that electrons bounce down and back from the center of the nucleus. When it touches down, the different colored light emits off of it.
-
They put in an electron and the light changes based off of the frequency. The electron falls and rises to this frequency based on how much energy its given.
-
He said that electrons just are just near the atom in a thick dense outside. They do not revolve just sit there.
-
Chadwick founded the neutron. He took the mass of a proton and saw that there was more mass to spare. He then figured there was a smaller atom that had neither positive nor negative charge.
