Formation of Atomic Theory- All matter is made up of tiny invisible particles (atoms).
-
Introduced the atomic theory into chemistry. All matter is made up of atoms and atoms are indivisible and indestructible. Compounds are also formed by a combination of two or more different kinds of atoms
-
Created periodic table of elements and used it to correct the properties of already discovered elements and to predict properties of elements that weren't discovered yet
-
Credited with the discovery of the proton
-
Credited with the discovery and identification of the electron and with the discovery of the first subatomic particle
-
Discovered energy quanta- Quantum Theory
-
Awarded Nobel Prize in 1923 for the measurement of the elementary electric charge
-
First to discover that atoms have a small charged nucleus surrounded by by empty space, and are circled by tiny electrons
-
Received Nobel Prize in Physics in 1922 for making contributions to the knowledge of atomic structure and quantum theory.
-
Used mathematical equations to describe the likelihood of finding an electron in a certain position- Also known as quantum mechanical model of the atom
-
Discovered the neutron in 1932 and received a Nobel prize for it in 1935
-
Developed theory of quantum mechanics which resulted in the discovery allotropic forms of hydrogen
