What occurs in Bohr's Model of the Atom when an electron moves down an energy level?

In Bohr's Model of the Atom, when an electron moves down an energy level, it releases energy in the form of a photon. This process occurs because the electron transitions from a higher energy level, which is less stable, to a lower energy level, where it is more stable. The energy difference between these two levels is emitted as a photon, a particle of light.

This phenomenon is a fundamental concept in quantum mechanics, illustrating the quantized nature of energy levels within an atom. Each energy level corresponds to a specific amount of energy, and the transition between these levels is not continuous but rather discrete.

When the electron makes this downward transition, the energy lost is exactly equal to the energy of the emitted photon, which can be observed as specific wavelengths of light. This explains the distinct spectral lines that can be seen when an element is heated or energized, as they correspond to the energies released by electrons transitioning between levels.
