Atoms arrange in diffenent conbluatias to make different compounds. He use mathematical models to discovery.

He used his imagination how he thought they looked.
as tiny little balls combination to make things.

Thomson

Mar 8, 1897

Thomson used a cathode ray tube to inferr that there are particles inside of every atom. This inference proved dalton's theory to be wrong.

Rutherford

Mar 7, 1909

Ernest Rutherford was another scientist that changed the atomic model. He felt that J.J. Thomson model was incorrect so he created a new one.

Bohr

Mar 7, 1913

He decided to make a new model based off of Rutherford's model, changed the orbit of the electron. Also, he created energy levels in the atom.

Heisenberg and Schrodinger

He was ban Austirian scientist that wprked with the Quanturmn model of the atom. He disagreed with theory, so he created his own.
