Dalton: Solid Sphere Model
The Solid Sphere Model was the first atomic model and was developed by John Dalton. He hypothesized that an atom is a solid sphere that could not be divided into smaller particles -
Thomson: The Plum Pudding Model
Summary. J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged soup. -
Rutherford: The Nuclear Model
Rutherford overturned Thomson’s model in 1911 with his famous gold-foil experiment, in which he demonstrated that the atom has a tiny, massive nucleus. -
Bohr: The Bohr (Planetary) Model
The Bohr Model is a planetary model in which the negatively charged electrons orbit a small, positively charged nucleus similar to the planets orbiting the sun -
Schrodinger: Quantum Mechanics Mode
The Schrödinger equation is a linear partial differential equation that governs the wave function of a quantum-mechanical system. It is a key result in quantum mechanics.
