Homework Help: Probability/Schrodinger's equation

  1. Jun 20, 2013 #1
    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 2[itex]a_{o}\ =\ 0.5291772083(19)\ \times\ 10^{-10}α\ m[/itex]?

    Would 0 4πr3ψ2dr/3 x100% be correct?

    No, it wouldn't even have correct dimensions. Why do you think that's right? Work it out from the three dimensional integral of |ψ|^2. Your differential factor is wrong.
