# Problem: Calculate the energy (J) change associated with an electron transition from n = 2 to n = 5 in a Bohr hydrogen atom.

###### FREE Expert Solution

In this problem, we are asked to determine 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:

$\overline{){\mathbf{∆}}{\mathbf{E}}{\mathbf{=}}{\mathbf{-}}{{\mathbf{R}}}_{{\mathbf{H}}}\mathbf{\left(}\frac{\mathbf{1}}{{\mathbf{n}}_{\mathbf{final}}^{\mathbf{2}}}\mathbf{-}\frac{\mathbf{1}}{{\mathbf{n}}_{\mathbf{initial}}^{\mathbf{2}}}\mathbf{\right)}}$

ΔE = energy related to the transition
RH = Rydberg constant

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

Given values: ###### Problem Details
