Chapter 6.3, Problem 1CP

Interpretation Introduction

Interpretation:

In a hydrogen atom, the energy of an electron in $n=3$ state is to be calculated.

Concept introduction:

The energy of an electron in a hydrogen atom is expressed as follows:

$E_n\text{ = }-2.18\times {10}^{-18}\text{ J}\left(\frac{1}{n^2}\right)$

Here, $n$ is an integer.
