Is Energy Conserved When an Atom Emits a Photon?

Click For Summary
SUMMARY

The discussion centers on the conservation of energy during photon emission from an atom. When an atom emits a photon, its energy decreases by an amount equal to the energy of the emitted photon. The total energy of the system, which includes the atom after emission and the emitted photon, remains constant, confirming the principle of energy conservation in quantum mechanics.

PREREQUISITES

When a photon is emitted by an atom is the energy of the atom conserved?
 
Science news on Phys.org
The creation of a photon leaving the atom must imply that the energy of the atom must have changed.
 
The energy of the emitted photon plus the atom after emission is the same as the energy of the atom before emission.
