Question

why are the shells in which electrons revovle called energy levels?

Open in App

Solution

Because electrons revolving in a shell are associated with certain fixed amount of energy. To jump to the next energy level electrons need to certain fixed energy and when it comes down it releases certain energy.

Thus shells are called or known as energy level
