Document Summary
Before this arose they knew there were electrons traveling around a proton filled nucleus. Laws of physics said electrons should spiral into nucleus. Only works for _____________ energy difference is given by: Bohr model energy levels the energy of a given energy level is given as: atomic number: so the difference in energy is. Rydberg equationif the energy of a given energy level is defined as en=-rh(1/n2). We can find the difference in energy shells by e nf-e ni. Either of these are often shown in text books. Use whichever you prefer but be sure not to mix them up. A free electron has e=energy of levels are negative, most negative and therefore lowest energy is n=1. E is positive if going from ___________ energy shell i. e. ground state to anything, 25 ect Words such as photon absorbed will be used. E is negative if going from _____________ i. e. anything to ground state, 52 ect
