Bohr’s Atomic Model: Description, Postulates and Limitations

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) WebBohr’s Assumption.
