Rutherford: The Nuclear Model
an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure. -
Bohr: The Bohr (Planetary) Mode
the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus -
Schrodinger: Quantum Mechanics Model
The Quantum Mechanical Model of the Atom. Energy Is Quantized. After Max Planck determined that energy is released and absorbed by atoms in certain fixed amounts known as quanta,
