How do we know that an electron can't be between an energy level?

Postby Radha Patel 4I » Sun Jul 07, 2019 5:35 pm

Why do energy levels have to be integers without decimals. For instance, the principle quantum number of an electron moves from energy level n=1 to n=2 when it absorbs light. Why couldn't this electron have moved to n=1.5? How do we know energy levels exist?

This is the basis of quantum mechanics, where the values are only discrete values, thus the "quantum" part. The energy of the photon must match the same energy to raise that electron to the next energy level, or else if it is lower or higher the photon will just pass through thus not being absorbed.

I may have missed this in lecture but can the electrons change levels?

they can only change levels when they get the exact amount of energy
