The normalized radial wave function, (41.2), for the 2p state of the hydrogen atom is R2p, = (1/√24a5) re –r/2a. After we average over the angular variables, the radial probability function becomes P(r) dr = (R2p) 2r2 dr. At what value of r is P(r) for the 2p state a maximum? Compare your results to the radius of the n = 2 state in the Bohr model.
