    Hi, I'm a Swedish student studying information technology with a great interest for physics and mathematics. I hope to be learn new interesting things and hopefully be able to help out a little too with the knowledge I have :)

    The electron is not a point charge sitting at the distance you gave from the nucleus. Quantum mechanically, the charge is "smeared out" into a distribution given by the electron wave function. If you do the calculation taking this into account, you should get the right answer.

    (I did not intend this to end up in introduction so I changed the thread to an introduction. Ehm should I revert back to the question or keep both. I screwed up D:)

    I know a little about the quantum smudge, yes, but shouldn't the radious stated in my textbook be the average distance? And thus work out the same way?
