Question

What happens after an excited electron jumps from a lower energy level to a higher energy level?

A. It permanently stays in that energy level.
B. It returns to the lower energy level with the emission of a lepton.
C. It returns to the lower energy level with the emission of a photon.
D. It returns to the lower energy level without any emission.

Answer 1

C) With the emission of a photon.

Answer 2

C. It returns to the lower energy level with the emission of a photon.

Step-by-step explanation:

Electrons absorb energy and jump from the lower energy state to the higher energy state. At the higher energy state the electrons are unstable, so they return to the lower energy state with the emission of a photon. The energy of the emitted photon is equal to the difference in energy between the excited and ground state.
