    Divergence theorem for a non-closed surface?

    Is there some way we can apply divergence (Gauss') theorem for an open surface, with boundaries? Like a paraboloid that ends at some point, but isn't closed with a plane on the top. I found this at Wikipedia: It can not directly be used to calculate the flux through surfaces with boundaries...

    Finding the probability (again)

    So, we have a hydrogen atom. What is the probability of an electron being found in a spherical shell with 0,01Å width and a radious of 0,35Å? By approximation, we can sonsider the value of ψ (1s) stable within the shell, and thus the chance is ψ2 x Volume. Right? Also, by considering 0,35Å...

    Probability/Schrodinger's equation

    We have a hydrogen atom in its ground state. What is the probability of an electron being found within a sphere (with nucleus being the origin) of a radius of 2a_{o}\ =\ 0.5291772083(19)\ \times\ 10^{-10}α\ m? Would 0∫2α 4πr3ψ2dr/3 x100% be correct?
