4 sentence of the importance
Bohr’s own research led him to theorize in a series of articles that atoms give off electromagnetic radiation as a result of electrons jumping to different orbit levels.
Bohr had to make a radical proposal.. the electron can only occupy certain stable orbits with prescribed energies
The electron orbit closed to the proton has the lowest energy. Energy is the needed to " pull " or " lift " the electron away from the proton, so orbits with larger radii have higher energies.
The energy source - light. The electron can also absorb a photon of light and use all of that photon energy to jump from a lower energy orbit up to a higher energy orbit
