Use the approximation, P r r r r Within r=0 to r=10-15m, we shall let r And we know that the Bohr Radius Plug in all the numbers. We obtain: P (b) n=2, l=1. Use the same approximation, P Where, R Plug in all the numbers. We obtain: P 6 10 We find that P P , because the angular momentum keeps the electrons away from the origin or to say there is a potential barrier.
