Homework Help: Orbital angular momentum possible values of an electron in a hydrogen atom

  1. Dec 4, 2012 #1
    1. The problem statement, all variables and given/known data

    What are the orbital angular momentum possible values for an electron in a hydrogen atom with a principal quantum number n = 3?

    2. Relevant equations

    [itex]L = \sqrt{l(l+1)}\hbar[/itex]

    3. The attempt at a solution

    Possible values for l are 0, 1, 2.

    So, substituting these in the equation above I get: 0, √2[itex]\hbar[/itex], √6[itex]\hbar[/itex].

    Is this the right answer?
