A "quantum" is a measure of energy that can "kick" an electron up one complete energy level within an atom. Applying, for instance, heat (thermal energy) to a substance will excite electrons to go "up" an energy level at a time.
You may note that heated things often glow or give off visible light. They also give off other forms of light (other wavelengths along the Electromagnetic Spectrum) such as infrared light.
How does a substance give off light anyway? This is an integral part of understanding what quanta are.
Energy is "invested" into electrons in "chunks" or quanta of energy. However many quanta of energy are applied to an electron to raise it up in energy level will be released when that electron drops back to its "ground state". This energy is given off in the form of photons. Photons are like "packages" of light.
In summary, a quantum is the amount of energy it takes to bring an electron from one energy level to the next higher energy level.
The quantum mechanical model is called the quantum theory.
The quantum mechanical model is the name of the atomic model in which electrons are treated as waves.

The model of the atom based on Quantum Theory is often called the "Quantum Mechanical Model" or the "Quantum Model." This model describes the behavior of electrons around the nucleus as probabilistic, rather than in fixed orbits.

Well, the conventional system of quantum mechanics can also be known as the Standard Model of Particle Interaction, or the Standard Model for short.
In the standard model, a quark and its antiquark have opposite quantum numbers.
The quantum mechanical model of the atom, also known as the electron cloud model, shows electrons as existing in certain regions of space called orbitals. These orbitals represent the probability of finding an electron in a specific location around the nucleus.
The Electron Cloud model
Now the quantum model is accepted.
