Question and answer
Q: The energies of electrons are said to be quantized. Explain what this means.
A: The motion of the electron is not free. The electron is bound to the atom by the attractive force of the nucleus andetc. [ Reference OR Electrons that are tied to a nucleus have an energy, which dictates how far and where they can "orbit" around the nucleus. If they have more energy, they change there orbit. Quantized means that they can't change there energy to any value, but have to move if
fixed jumps. One effect of this is that an electron in orbit can only absorb photons that will move it to one of its fixed energy levels. Electrons not tied to a nucleus can have any energy level. reference ]
