Evaluate r), the expectation value of r, for the 2p state of the hydrogen atom. in a separate calculation determine the distance from the nucleus where the probability of finding the electron in the 2p state is at its maximum. what is that distance for he? hint for this problem it is easiest to start with the radial function, r,(r), written explicitly for any nuclear atomic number z
