Quantum number in hydrogen atom

    1. The problem statement, all variables and given/known data

    2. Relevant equations
    Quantum mechanical model of atomic structure

    3. The attempt at a solution
    Why all sets are allowed?
    H atom only got one e- which only one orbital should be there, isn't it?
    If there aren't second or more e- , no second orbital or higher number of orbital, how comes there is higher number of shells (principle n) ? Hence as do the the number of angular momentum (l) for subshell and magnetic (ml) for the variety of orientation?

    I am a newbie to QM, who learnt only Bohr's model in high school.
    Thank you very much.

    Electron can get excited. You are thinking in terms of the the lowest energy level it can occupy - which is not a bad starting point, but it is not a whole story either. When it gets excited it can jump up to any orbital, described by any set of valid quantum numbers.
