Subjective Type

What is the experimental evidence in support of the idea that electronic energies in an atom are quantized?

Solution

Classical mechanics fails when applied to microscopic objects like electrons, atoms and molecules, etc.
This is because the classical mechanics ignores the concept of dual nature of matter.
The branch of science that takes account this dual behaviour of matter is called quantum mechanics.
