We are asked to calculate the energy (J) change associated with an electron transition from n = 2 to n = 5 in a Bohr hydrogen atom.

To calculate the energy required for the electronic transition, we will use the Bohr Equation shown below which relates electronic transition to the energy:

ΔE= -RH1nf2 -1ni2  

ΔE = energy related to the transition
RH = Rydberg constant

ni = initial principal energy level
nf = final principal energy level
