Does It Mean for a Property to Be Quantized?

The fundamental notion that a physical property can be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum.

What does it mean if something is quantized?

1 : to subdivide (something, such as energy) into small but measurable increments. 2 : to calculate or express in terms of quantum mechanics.

How do you know if something is quantized?

In the simplest sense, if something is “quantized”, that means it can only take on certain specific values, rather than a continuous range of values. For example, the energy that an electron can have when it's bound to an atom is quantized.
