Applications of Bohr's Second Postulate

Bohr’s second postulate states that electrons undergo transition, where they jump from one energy level (stationary state) to the next.

This stands correct for nuclear medicine as radioactive nucleotides release photons which are picked up by the PET scan only when an electron transitions from a higher energy level to a lower one resulting in the electron losing energy and releasing a photon of light equal to the energy difference between the stationary states (1 electron).

This explains the bright lines on the emission spectrum that can be visualized if the radionucleotides or annihilation of electrons were to be graphed and presented. That released light is also the rays that are picked up by the PET scanner to create images of the internal body of the patients.

Without Bohr’s second postulate the nucleotides would never be possible to create and hence use for nuclear medical imaging, showcasing the immense importance and implementations of atomic structure in such innovative and groundbreaking technologies.
