The Conditions Under Which Atoms Will Emit Light

Describe the conditions under which atoms will emit light

Electrons in an atom exist in their stable ground state. If the electrons absorb a quantum of energy by heating or applying a potential difference, they become excited. This causes an electron to jump from its ground state to a higher energy level called an excited state. However, electrons cannot exist between the quantized energy levels. As a consequence, they release a quantum of energy as they return to their ground state.
