Question

I have answered question 8 and 9, but am having a hard time answering why they are different.

Calculate the expectation value for (r) for the ground state radius of the hydrogen electron. The radius operator is simply, r. You can use Wolfram Alpha to help with the integral or you can use the formula . n! x"e-axdx = an+1. Calculate the radius of maximum probability for the hydrogen 1s orbital. Don't forget that the r' factor is required when interpreting the probability density in spherical polar coordinates. . o. Comment on the difference between your answers between questions 8 and 9. Why are they different? If it is helpful, look at the plot on page 130.
