Orbital Angular Momentum: For an electron in the M (n = 3) shell, find (a) the largest possible orbital angular momentum it can have, and (b) the smallest possible orbital angular momentum it can have. Express your answers in SI units, and for each case indicate the subshell (s, p, d, ...) of the electron. (h = 6.626 × 10-34 J ? s)
What will be an ideal response?
(a) 2.583 × 10-34 kg ? m2/s, d subshell, (b) 0 kg ? m2/s, s subshell
