A hydrogen atom is in the stationary state (n, I, m) = (5, 3, 1)
What is the angle between the angular momentum vector L and Lz?
Give you answer to 3 significant figures and in units of degrees, but do not include the
units in your answer.
a) How many distinct angles from the vertical axis can the orbital angular momentum vector L make for an electron with l = 7?
b)Calculate the smallest possible angle the L can make with respect to the vertical axis. (Hint: The smallest angle occurs when ml takes the maximum allowed value. Sketch L in that case and compare the vertical component, which is related to ml, to the magnitude of L, which is related to l.)
Calculate the value of <r> for the states of the hydrogen atom with n = 2 and l = 1, and for n = 2 and l = 0. Are the results surprising you? Explain your answer?
