Believed that atoms where uniform, solid, hard, in-compressible and indestructible.
Everything is composed of atoms. -
Born: 09/06/1766
Died:07/27/1844
He proposed that all matter is made of tiny indivisible particles called atoms.
Scientist came up with atomic neutrons, protons, and electrons from his theory. -
Born: 02/08/1934
Died: 02/02/1907
Made the periodic table!
He "periodically" gets mentioned in science class -
Born: 12/18/1856
Died: 08/3/1940
Discovered the first subatomic particle, the electron while researching cathode rays.
Scientist know there are particles smaller than atoms. -
Born: 10/07/1885
Died: 11/18/1962
Propsed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus.
Scientist know that electrons travel in separate orbits around the nucleus. -
Born: 08/30/1971
Died: 10/19/1937
He performed the first artificially induced nuclear reaction, as a result discovered the hydrogen atom.
Scientist know the mass of the atom is concentrated in its nucleus. -
Born: 08/12/1887
Died: 01/04/1961
Theorized that the behavior of electrons within atoms could be explained by treating them mathematically as waves.
Today he is most famous from The Big Bang Theory of Sheldon explaining Schrodinger's Cat. -
Born: 12/05/1901
Died: 02/01/1976
Formulated quantum mechanics in terms of matrices and in discovering the uncertainty principle.
Cosmic ray theories. -
Born: 10/20/1891
Died: 07/24/1974
Discovered the neutron!
We know positively charged protons and neutral neutrons bound together as the atoms nucleus, with negatively charged electrons occupy energy levels surrounding the nucleus.
