Chapter 6.3, Problem 2CP

Interpretation Introduction

Interpretation:

The $\Delta E$ of an electron that goes from $n=5\text{ to }n=1$ is to be calculated.

Concept introduction:

The Rydberg formula for Bohr’s model is as follows:

$\Delta E\text{ = }-2.18\times {10}^{-18}\text{ J}\left(\frac{1}{n_f^2}-\frac{1}{n_i^2}\right)$

Here, $\Delta E$ is the energy level difference, $n_f$ is the final energy level of the electron, $n_i$ is the initial energy level of the electron, and R is the Rydberg constant.
