The document summarizes the quantum model of the atom. It describes how electrons exhibit wave-like properties and have quantized wavelengths. The Heisenberg uncertainty principle states that it is impossible to know both the velocity and position of an electron at the same time. Schrodinger's wave equation defines quantized energy levels and the probability of finding an electron. Electrons occupy orbitals defined by four quantum numbers that specify the electron's unique "address" within the atom.
