E = = (13.6 eV) = -5.39 eV, which we can rearrange to find Z’ : Z = 4 ( (-5.39 eV/-13.6eV) = 1.59. Comparing the answers to d. and . e, we can say that the outer electrons see a reduced nuclear charge but the nucleus is only partly shielded by the inner electrons. Workshop Tutorials for Physics.

We need to convert our answer to kJ mol–1. Li2+ has three protons in the nucleus and hence a +3 nuclear charge, making Z = 3. We need to convert our answer to kJ mol–1. 1.49 Equation 1.15 yields the energy of the photon absorbed for different transitions. For an emission, Equation 1.15 can be written:
