John Dalton Marble Model:
When John Dalton created the Marble Model he stated/discovered that Atoms are small little balls that can not be destroyed, also that Atoms combine together and form compunds in whole number ratios. This is important to the evolution becasue it was a starting point to the Atom and gave other scientists a base of knowledge. -
Period: to
Evolution of the Atomic Model

J.J Thomson Plum Pudding Model:
As the secon Disoverer on this list J.J was the first scientist to find a electron. Electrons are solid small balls that are positively charged with negative specks in it. Electrons are located in the Nucleous. This is important to the evolution because it added on to the Atom and gave it different aspects of it and gave a positive charge to it. -
Ernest Rutherford Model:
Unlike J.J who discovered the Electron, Ernest discovered Protons and Nucleus. He stated that Atoms are just little spheres that are empty space. Also that electrons are not in the Nucleus and instead float around it. This is important to the evolution because it gave them a base on the nucleus and added a new charge of atoms. -
Niels Bohr Solar System Model
Neils Bohr was the person to discover E- in energy leves around the entire Nucleus. He was the fourth scientists to contribute into the evolution. His model was unique because it gave the neucleus and all the charges and then it also showed the outer layers. This is important to the evolution because it got them one step closer to there final product and gave different facts about it. -
Erwin Schrodinger Electron Cloud Model
Erwin discovered that all levels of energy are not circular. Electrons(-) can change energy levels. Darker parts of the Atom are more likely to contain Electrons. This is important to the evolution becasue it gave an Electron Cloud and added to the Atom
