Answer
Energy is quantized in some systems, meaning that the system can have only certain discrete values of energy and between those values, other values of energy are not permitted.
The quantization of energy is most important for particles of small mass such as molecule, atom, or subatomic particle confined to small regions of space. The
effects of quantization becomes most important for microscopic system, when we focus on rotational to vibrational and then to electronic motion of the subatomic particle.
