What is the definition of quantization in physics and how does it relate to the behavior of particles at the quantum level?

Quantization in physics refers to the process of restricting a physical quantity to discrete, specific values rather than allowing it to vary continuously. In the context of quantum mechanics, quantization is crucial in understanding the behavior of particles at the quantum level. It explains how certain properties of particles, such as energy levels and angular momentum, can only exist in discrete, quantized amounts. This concept helps explain phenomena like the wave-particle duality and the probabilistic nature of quantum mechanics.
