WebAbstract. Sommerfeld's extension of Bohr's atomic model was motivated by the quest for a theory of the Zeeman and Stark effects. The crucial idea was that a spectral line is made up of coinciding ... WebSo the difference in energy ( ΔE) between any two orbits or energy levels is given by ΔE = En1 − En2 where n1 is the final orbit and n2 the initial orbit. Substituting from Bohr’s equation (Equation 7.3.3) for each energy value gives. ΔE = Efinal − Einitial = − ℜhc n2 2 − ( − ℜhc n2 1) = − ℜhc( 1 n2 2 − 1 n2 1)

According to Rutherford’s model, a nucleus is positively charged and is surrounded by negatively charged electrons. Bohr modified this model by adding that the electrons travel in fixed circular orbits around the nucleus.
