Question

How does the energy of an electron change when the electron moves closer to the nucleus?

Answer 1

The energy of the electron reduces as it moves closers to the nucleus. This is because it moves from a higher energy orbital to a one of lower energy. It does this by releasing a photon with the energy difference of the current energy level, and the energy level it drops too.

Answer 2

The electrons increase their energy and speed as they get closer to the nucleus.

Step-by-step explanation:

An explanation has to do with the energy or speed of the electron. When the electron approaches the nucleus, it increases its energy and speed, moving in a region around the nucleus at a speed that is high enough to balance the attraction it exerts so that the electron does not collide with the nucleus.
