Question
The two waves below have the same height. Answer questions 1-3 about these two waves. Which wave has the largest energy? Which has the greatest wavelength? Which has the highest frequency? Rewrite the following electromagnetic radiation types in increasing order of energy (most energy to the right). Use the abbreviations to save time. gamma ray (GR), radio waves (RW), ultraviolet (UV), infrared(IR), visible (VIS) Why do electrons in atoms only absorb photons with a specific amount of energy? Write the full electron configuration for the sulfur atom (S). Write the condensed electron configuration for the atom with atomic number 37. What atom has 3d^9 as its last subshell? Draw the orbital box diagram representing 3d^9 and give the four quantum numbers of its last electron.Explanation / Answer

The electrons in an atom can only occupy certain allowed energy levels. This was one of the early results of quantum mechanics. Classical physics predicted that a negatively charged electron would fall into a positively charged nucleus emitting a continuous spectrum of light as it did so. This is obviously not the case as if it were there would be no stable atoms. It was discovered later that this didn't happen because electrons can only occupy discrete energy levels within the atom.
When an electron drops from a higher energy level to a lower one, the excess energy is emitted as a photon of light. The wavelength, of the photon is inversely proportional to the change in electron energy:
=c×hchange in electron energy
Where c is the speed of light in a vacuum and h is Planck's constant.
Only certain energy levels are allowed, so only certain transitions are possible and hence specific
