Consider an electron in a one-dimensional box the size of a nucleus with one proton Hydrogen, 10-14m.
a) Approximate its ground state energy
b) Approximate the coulombic energy V between the proton and electron from V = -e2/4pir
c) Could the electron be held in the nucleus by the proton? Why or why not
d) See if you can come to the same conclusion using the Heisenberg Uncertainty Principle.
