It isn't so much a matter of there being a given "quantum of energy" as much as energy is quantized. This means that particles that behave quantum mechanical laws can only have certain values of energy and not the values in between. The most popular example of this is an electron in an atom. Quantum theory tells us that the electron can be in it's ground state energy, which has a given value, or it's first excited state, which has another given value, or any higher excited state. However, you cannot observe an electron with an energy value in between the ground state and first excited state, or between any two consecutive excited states. This is what it means to have quantized energy: only certain discrete values are allowed.
exact, whole number amount of energy needed to move an electron to a higher energy level
True, a photon is a quantum of energy, E=hf.
In physics, quantum is a discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property.
AnswerZero-point energy (not to be confused with Vacuum Energy) is the lowest possible energy that a quantum mechanical physical system may have and is the energy of the ground state. This energy comes from the fact that after you remove all thermal and kinetic energy from an atom there is still quantum mechanical harmonic vibration that arises due to the Heisenberg Uncertainty Principle. This energy, so far, can not be taken away from a system.
Photon
No. A quantum is a small and indivisible unit of SOMETHING, which might be energy, charge, spin, or several other things.
In the universe energy, matter and go as per quantum. Energy is released in quantum of photon. Electron has a quantum mass. Proton has quantum mass. Both has a quantum charge. Neutron has a quantum mass. Speed of light is a quantum. Big bang is a quantum event essentially occurring at particular mass. It takes a quantum energy for shifting of electrons from one shell to other. In photo-luminescence light energy is released in quantum.

Bohr's model explains how electron transitions cause hydrogen's atomic emission spectra. The quantum model is a 3-d view of the atom, which shows an electron's energy levels and sublevels and the probability of an electron's location, proven with complex mathematics.

These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
