-
He came up with what he called the theory of the universe. He was the first person to use the term Atom as well.
-
He denied the existence of atoms, and criticized Democritus. He was so great in science that his denial of atoms went unchallenged for nearly 2000 Years.
-
Was one of the first to use an analytical balance to monitor chemical reactions. He studied the thermal decomposition of mercury and helped develop the atomic theory.
-
He was the first to adapt Democritous' theory into the first atomic model. He discovered the atomic theory.
-
He is a physicist who discovered the electron. He used his research on cathode ray tube technology in his discovery and found out about negative charge and that negative charge is inside an atom.
-
Oil drop experiment determined the charge and the mass of an electron.
-
He set up the Gold Foil Experiment and created the nuclear model. He founded and named the nucleus.
-
He answered the questions of Rutherford's model with why electrons did not collapse into the nucleus. He helped with the model that became known as the Rutherford-Bohr Model.
-
revolutionary physicist who used Heisenberg's uncertainty principle to come up with the atomic model that we still use today; the Schrodinger atomic model aka the cloud model.
-
Proposed the Principle of Indeterminacy. Described atoms by means of formula connected to the frequency of spectral lines.
-
He came up with the quantum theory and predicted the wave nature of electrons.
-
He used alpha particles to discover a neutral atomic particle with a mass close to a proton. Then discovered the neutron.
