Question

What is quantization?

Answer 1

Quantization is the concept that a physical quantity can have only certain discrete values. Electrical charge, energy, light, angular momentum, and matter are all quantized on the microscopic level. They do not seem quantized on the macroscopic scale because the size of the steps between each possible value is so small. For example, the matter is quantized because it is composed of individual particles that cannot be subdivided; it is not possible to have half an electron. Also, the energy levels of electrons in atoms are quantized. The electron's energy can have only certain values, and all intermediate values are prohibited.
