What can be expected as results for a set of position and momentum measurements of an electron in a hydrogen atom?
I believe that for the position, we can expect something depending on the radial probability density (shown in the figure for levels $1s$, $2s$ and $3s$).
If I'm wrong, please correct me. On the other hand, with regard to the set of measures of the momentum, I do not know what can be achieved. Is there a way to estimate this or can I just expect the uncertainty principle to be obeyed?
