-
He said that all matter is made up of atoms. Also, he said that they are invisible and can not be broken down.
-
He made the atomic theory. The theory says that matter is compose of atoms that all of the same atomic weight.
-
Was the first to discover the electron.
-
Determined the charge of an electron.
-
Determined that all the mass in a atom is in a small positive charged ball in the center of the atom called the nucleus.
-
He developed the Bohr Model which had a nucleus in the model with electrons traveling in a circular motion around it.
-
Albert made the discovery of the law of the photoelectric effect. The law says that electrons are emitted from solids. liquads, and gases.
-
He suggested that all matter has wave wave properties. This is called wave particle duality
-
He introduced the Pauli Principle or exclusion principle. It involved the spin theory.
-
Made the Schrodinger equation, an equation that deals with waves and how they control the motion of small particles.
-
He helped create the quantum model. The model proves that you can't find the exact location of electrons.
-
Discovery of the neutron.
