Chapter 39, Problem 60P

To determine

To find:

a) The energy difference between the electrons ground state and its first excited state

b) The  quantum number $n$ would the energy difference between adjacent energy levels be $1.0$ $eV$ which is measurable, unlike the result of (a)

c) The multiple of the electron’s rest energy would give the electrons total energy.

d) Would the electron be relativistic?
