Quantum Mechanics is also known as quantum physics or quantum theory. The Quantum Atomic model is the most recent model of the atom. It's based on quantum mechanics.Quantum numbers are quantum solutions to quantum equations and are used to find energy level an electron is in. The magnetic quantum number indicates that a region within a sub-level called an orbital where two electrons reside. The most common way to describe electrons in atoms according to quantum mechanics is to solve the Schrödinger equation for the energy states of the electrons within the atom. When the electron is in these states, its energy is well-defined but its position is not. The position of an electron is described by a probability distribution map called an orbital.

After Max Planck determined the enery is released and absorbed by atoms in certain fixed amounts known as Quanta, Energy is Quantinized.
