Question

How are photons emitted by atoms?

Answer 1

The photon is emitted with the electron moving from higher energy level to a lower energy level. It decreases energy and the atom emits

Answer 2

Step-by-step explanation:

When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
