John Dalton
"Father of Chemistry" helped prove the Atomic Theory -
Johann Dobereiner
One of the first people to find the chemical properties of an element and he found the chemical properties for Carbon. -
Dmitri Mendeleev
Proposed the idea of a perodic table yet there was only eight collums to this table. By doing so he had predicted the the chemical properties and atomic masses. -
J.J Tomson
Descovered the Cathode and Anode charges He also creater a cathode ray. Also created the plum pudding modle. -
Einstien
Created the most used equation for energy E=mc2 -
Henry Moseley
Conducted X-ray experiments to find out if an element has a positive or negitive charge. -
Max Planck
Wins the Nobel Prize for Physics also descovers that energy thavels through photons and quanta. -
Lord Rutherforg
Gold Foil Experment, used a peice of extreamly thin gold foil and shot radition beams at it so see if the rays would pass throught the foil or not. He ended up proving Tomsons Therory wrong because of his therory -
Robert Millikan
Createda design that could tell the charge of and atom. Also investigated the cosmic rays. -
Bohr
Changed the electron placement theory completly because of the experment that Rutherford had done. -
Wolfgang Pauli
Wins NobelPrize in Physics also introduced the theory of the fourth quantum number.
