-
All matter is composed of atoms. He pictured atoms as indestructable particles with no internal structure. (Solid Sphere Model)
-
He discovers the electron, a negaticely charged particle, and creates "Plum-Pudding" model.
-
Theory of relativity, which laid basis for atomic energy release.
-
Discovered an accurate determination of charge of an electron and that all electrons have the same charge.
-
Discovered the nucleus is dense with positive charge. (Planetary Model)
-
Electrons orbit Nucleus. (Planetary Model)
-
Came up with general theory for electrons: "Wave Mechanics."
-
Created Theory of Quantum Physics. Use matrix equations to determine velocity and position of electrons.
-
Discovered how to estimate where electrons are in an atom.
-
Discovers the nuertron, a neutral charged particle in the nucleus.
-
Discovered the neutrino, a massless and neutral particle that carries off energy in radioactive disingration. Pauli exclusion principle-Structure in terms of energy levels. (Nuclear Shell Model)

-
A greek phiosopher that figured out that all things are composed of atoms. (Origin of Atomic Theory)
