Question

calculate the ground state energy of an electron confined in an one-dimensional box of length 20nm.​

Answer 1

Answer:

A simple expression for the energy of an electron in the hydrogen atom is:

E=−13.6n2 where the energy is in electron volts.

n is the principle quantum number.

So for an electron in n=1 :

E=−13.6eV.

To convert to joules you can x this by 1.6×10−19.
