Definitions for "Quantum Mechanics"
The branch of physics which deals with the behavior of matter at the level of the atom, the nucleus, and the elementary particle. At this level, energy, mass, momentum, and other quantities do not vary continuously, as they do in the large-scale world, but come in discrete bundles (quanta) in which radiation and other forms of energy occur. See "Quantum Theory".
the laws of physics that apply to objects on the atomic scale.
it is a mathematical explanation for the behavior of electrons in atoms based on quantum theory, which states that the atomic particles are quantized, having discrete properties; energy levels, rotational energies, etc. It is an explanation for many observed phenomena and for explaining the natural world. Understanding of quantum mechanics allow for explanations of atomic properties and wave-particle duality, and provides an understanding of the interaction between electromagnetic radiation and matter.
