Question:

A singly ionized helium atom has an electron in the n = 4 state. What is the electric potential energy of the electron?

Potential Energy of an electron:

Potential Energy of an atom is a result of excitation of electrons from a lower energy state to a higher energy state. The higher the excited state (n =4 here) higher the potential energy is.

It is given as -{eq}\displaystyle (P.E)_n = 2E_n\\ {/eq}

Answer and Explanation:

Given - z = 2 and n =4

Total Energy is given as{eq}\displaystyle E_n = -13.6\,ev\left(\frac{z^2}{n^2}\right)\\ \displaystyle E_4 =...
