__**Ernest Rutherford**__ **Democritus** Nationality: English Name of Model: Rutherford Year of Discovery: 1911 model Description: He discovered that most of an atom is empty space. Citation(s): Science Explorer Grade 8 Nationality: Austrian Name of model: Schrodinger’s wave Year of discovery: 1926 Short description of discovery: Schrodinger’s wave is a mathematical equation of wave mechanics that assumes a non-relativistic wave equation that over rules how electrons act with in a hydrogen atom.

James Chadwick Cheshire. In 1932, James Chadwick proved that the atomic nucleus contained a neutral particle, which had been purpose more than a decade by Ernest Ruthford.

The name of his model was neutron particle; he discovered his model in 1932. [[image:http://users.zoominternet.net/~even/e_noyau.JPG]] /
__**Edward Frankland**__ Nationality: England Name of Model: Valency Theory Year of Discovery: 1852 Description: The Valence is the number of bonds made of an atom in a certain element. Citation: [] []) []

John Dalton John Dalton was born September 6, 1766 in CumberlandEngland. His atomic model was called the billiard ball model because he thought the atoms looked like tiny little spheres. He discovered the atom in 1803. On the 23rd of October he wrote his essay on the compact for atomic weights and absorption of gasses. In his Theory there where four basic ideas: 1: chemical elements are made of atoms 2: atoms are identical in there masses. 3: atoms of different elements are different masses 4: Atoms can’t be destroyed or created.
