Then that atom will emit two electrons, but it will not be stable yet.

As a result, every atom emits a different set of photon energies.

Its half-life of 4.5 billion years means that only a few atoms emit radiation at a time.

Hot atoms emit more energy because they have more extra energy.

These atoms emit photons at the frequency of the control light field.

These atoms emit gamma rays, which reveal the chemical structure of the objects.

Run them forward, and you see an atom emitting a photon.

A driven atom cannot emit two photons at once, and so in this case .

Also, it was noted that excited atoms emit radiation with discrete frequencies.

With the addition of a neutron, those atoms emit radiation.
