Quantum Chemistry 7.7 - Hydrogen Atom Radius (Old Version)

[TMPChem]

Hi Forrest, I can't directly reply to your comment (possibly do to your Google+ settings), so I'm responding here.

The integral from 0 to 2pi of d(phi) is 2pi. The integral from 0 to pi of sin(theta)d(theta) is 2. The product of these is 4pi, as is seen in many problems of spherical symmetry, such as the denominator of Coulomb's law.

As far as I can tell the line in purple on the left is correct. I did not hear an incorrect reference as 11:55, although I may have misspoke as some other point in the video.

Thank you for the video. It helped me make sense of my homework!

In the video at 11:55, you say the integral of "d-phi" from 0 to π is 2π. I was wondering if the bonds were wrong or if they should correspond to the bounds for the expectation values?

You are seriously, and this is not an exaggeration, saving my grade right now.

I e-mailed the professor about the set up for this problem. And they did not even answer my question.

You explain everything so well and without the theoretical nonsensical jargon regarding the theory. My professor just wants us to punch out calculations but spends 4/5 of the time explaining the theory we will not use. It is pretty frustrating.

Out of curiosity are you a professor or student in this subject matter? Again, thank you!

i'm trying to find out which hydrogen-like element something is, given that it has single electron and has an observed radial node in 3px orbital at a given radius. I'm assuming that <r> is the given radius and you solve for Z using the real wavefunction of the 3px?
