I have rephrased the question posed: what agents determine the Energy of an Orbital in atoms??
To: What parameters determine the spectra observed when atoms and their associated electrons are excited? The Bohr treatment of the atom provides a simplistic, but incomplete answer. The Schrodinger treatment provides more depth.
The Bohr treatment proposed that electrons were particles in orbit around a massive nucleus. The basic Bohr assumption was that if an electron dropped to an orbit closer to the nucleus it had to give off energy in the form of radiation, or if it moved to a higher orbit it could only do so if it were provided with the proper amount of energy in the form of radiation [that it absorbed].
The Bohr treatment was remarkably successful in explaining the spectrum of the excited hydrogen atom.
The Bohr treatment is available is a reasonably accessible format at: http://www.colorado.edu/physics/2000/quantumzone/bohr.html
The Schrodinger proposed that electrons are actually waves and occupy orbitals of a variety of shapes. The Schrodinger treatment is available in a reasonably accessible format at: http://www.colorado.edu/physics/2000/quantumzone/schroedinger.html
These were the first two of perhaps 20,000 sites listed when I Googled on “Bohr’s atom”. Googling on Schrodinger’s atom gave a list of about 200. I think you can find the answers to your questions at these sites and links provided at these sites.
I think the treatment given at these two sites is accessible and can be trusted. A sampling of some of the other sites showed that some of the treatments border on “mystical” and cannot be trusted.
