Dalton Model
John Dalton's atom model was a small, unyeilding, indivisible ball. He believed that while all atoms conformed to this uniform makeup, atoms varied in mass, creating different elements. -

Models of the Atom
-
Thomson Model
After his discovery of the electron, J.J. Thomson created a new model of the atom. This model featured a giant sphere, positively charged. Also, electrons scattered sparingly. Sources have compared his model to the likes of muffins and puddings. -
Nagaoka Model
A positively charged sphere circled by electrons became Hanataro Nagaoka's model for the atom. The movements of the electrons mimicked the planets of our solar system. -
Rutherford Model
Empty space played a dominant part in Ernest Rutherford's model of the atom, which consisted of a tiny, positively charged sphere that was surrounded by electrons that wove circlr paths randomly around it. -
Bohr Model
The Bohr model, created by Niels Bohr, was neater than Rutherford's. He beleived that electrons orbited their nucleus in defined, organized patterns. The result could be compared to an onion, or the rings inside of tree trunks. -
Chadwick Model
The neutron fell out of obscurity when James Chadwick discovered the part they play in atoms. This cleared a tiny patch of confusion about the behavior of atoms in relation to their mass. -
Modern Model
In this most recent model, which has resulted because of more than 80 years of scientific inquiry, electrons bunch up around a nucleus, creating a cloud-like effect. The electrons, however, are very complex, fast, and we are unable to detect them.
