When an excited electron spontaneously emits a photon, which energy transformation takes place
notka56 [123]

Given what we know, we can confirm that when an excited electron spontaneously emits a photon, the energy released is electromagnetic energy.

<h3>What is a Photon and what energy does it release when being emitted?</h3>
  • A photon is a particle.
  • This means that it is one of the smallest forms of matter that we can study.
  • Photons form electromagnetic fields.
  • Therefore, when being emitted by an electron, photons release electromagnetic energy.

Therefore, we can confirm that when an excited electron spontaneously emits a photon, the energy released is electromagnetic energy due to the properties of the photon being emitted.
