jan 1, 1926 - Quantum model of the atom
Description:
Referred to as the "wave" model. This model proposed the following - electrons do not move about the atoms nucleus in a definite pattern, impossible to determine the exact location of an electron, the probable location is based on its energy, energy levels are divided into 4 sublevels and each sublevel is made up of several pairs of electrons called orbitals and this model shows how electrons move randomly in electron clouds called orbitals.
