States that everything is composed of atoms
-
Created the Atomic Theory
1. Elements are made of atoms
2. Atoms of a given element are identical
3. Atoms can't be created or destroyed
4. Atoms form chemical compounds by combining with other elements
5. Atoms are combined, seperated, or rearranged in chemical reactions -
Photoelectric effect stating that electrons can be released from atoms by means of light absorption. Also states that atoms emit photons.
-
Discovered the electron with his expirements using cathode rays. Created the Plum Pudding model of the atom.
-
First to reveal the existence of the nucleus using the gold foil expirement. He also disproved the Plum Pudding model.
-
Discovered the charge of an electron using an oil drop expirement. Created the molecular orbital theory.
-
Created the model for a hydrogen atom depicting the nucleus of the atom having a positive charge with electrons orbiting around it in specific patterns. Also known as the planetary model.
-
States that subatomic particles are mor like waves than particles. Specifically electrons
-
States that 2 electrons can't occupy the same quantam space at the same time. Helped create the nuclear shell model.
-
Created the electron cloud model using equations that deal with electrons and waves.
-
Created the Uncertainity Principle. Stating that it is impossible to mathematically find the momentum of an electron.
-
Discovers the neutron. Neutrally charged particle.
