D)It loses gravitational potential energy.
E)It exchanges gravitational potential energy for kinetic energy.

Question

Quizplus · Accepted Answer

When an electron in an atom jumps from a higher energy level to a lower energy level, it emits a photon equal in energy to its energy drop. The energy released as a photon is equal to the difference between the energy levels of the two electron shells involved.
