Question

According to the quantum mechanical picture of the atom, whichone of the following statements is true concerning the magnitude ofthe angular momentum L of an electron in the n =3 level of the hydrogen atom?

a. L could be 0.225h or0.390h.
b. L is0.318h.
c. L could be 0.225h or0.276h.
d. L could be 0.159h or0.318h.
e. L is 0.477h. According to the quantum mechanical picture of the atom, whichone of the following statements is true concerning the magnitude ofthe angular momentum L of an electron in the n =3 level of the hydrogen atom? L could be 0.225h or0.390h. L is0.318h. L could be 0.225h or0.276h. L could be 0.159h or0.318h. L is 0.477h.

Explanation / Answer

The magnitude of the angular momentum is given by           |L| =(l(l+1)) (h/(2)) For n=3   l= 2, 1           |L| = 2   (h/(2))   or 6   (h/(2))                   =0.225h or 0.390h
