Dalton: Solid Sphere Model
The Solid Sphere Model was the first atomic model and was developed by John Dalton in the early 19th century. He hypothesized that an atom is a solid sphere that could not be divided into smaller particles -
Thompson: The Plum Pudding Model
The Plum Pudding Model is a model of atomic structure proposed by J.J. Thomson in the late 19th century.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
The Bohr Model of the atom is very much like our solar system, with a sun as the center like the nucleus of the atom and the planets locked in defined orbits like the electrons locked in orbits around the nucleus. -
Schrodinger: Quantum Mechanics Model
Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This atomic model is known as the quantum mechanical model of the atom.
