Probably the best answer is Max Planck, who discovered that energy was quantized.

True, a photon is a quantum of energy, E=hf.
Specific quantity of energy
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.

True, a photon is a quantum of energy, E=hf.
The amount of energy needed to move an electron from one energy level to another is called a quantum.
Quantum
The quantum number for that energy level.
