Dalton: Solid Sphere Model
hypothesized that an atom is a solid sphere that could not be divided into smaller particles. He came up with his theory as a result of his research into gases. -
Thompson: The Plum Pudding Model
Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom. -
Rutherford: The Nuclear Model
The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun. -
Bohr: The Bohr (Planetary) Model
depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus in structure to the Solar System -
Schrodinger: Quantum Mechanics Model
This atomic model is known as the quantum mechanical model of the atom.
