An electron in a hydrogen atom is described by the radial wave function given by with energy Hint: R32 (r): 6. = 4 p. 8130 a3/2 a2 E3 = e 1 8 3 where the constant a is the Bohr radius. Calculate the expectation value of radius, (r), the most probable radius, and the maximum radius allowed classically. [4 marks] -r/(3a) x" exp(-x) dx = n! where n is a non-negative integer
