Quantum Definition in Physics and Chemistry:

In physics and chemistry, a quantum is a discrete packet of energy or matter. The term quantum also means the minimum value of a physical property involved in an interaction. The plural of quantum is quanta.

For example: the quantum of charge is the charge of an electron. Electric charge can only increase or decrease by discrete energy levels. So, there is no half-charge. A photon is a single quantum of light.

Light and other electromagnetic energy is absorbed or emitted in quanta or packets.

The word quantum comes from the Latin word quantus, which means "how great." The word came into use before the year 1900, in reference to quantum satis in medicine, which means "the amount which is sufficient".
