The anomalous Zeeman effect occurs because electrons have intrinsic spin, and when placed in a magnetic field, lose their degeneracy for the __________ states with different ________ . Fill in the missing words.
  a.2J + 1, m_J
  b. 2S + 1, J
  c.L + S, _l
  d. l + s, _s
  e. j - s, m_j

Question 2

Choose the statement below that does NOT help explain why the ionization energy of cadmium is so much larger than that of indium.
 

a.The energy required to remove an electron from a filled subshell is much larger than the energy required to remove an electron from a nearly empty subshell.
  b. The atomic radius of indium is larger than that of cadmium.
  c. Electrons in the 4d subshell spend more time inside the closed shells than does the additional 5p electron and therefore are more shielded.
  d. The additional electron in the 5p subshell is at higher energy and therefore easier to remove from the atom.

Answer to Question 1

a.
Each state with a total angular momentum of J has a degeneracy of the 2J + 1 states with a given m_J. Since m_Jranges from -J to J, there are 2J + 1 values possible and approximately degenerate. When placed in an external magnetic field, the states split due to the anomalous Zeeman effect.

Answer to Question 2

c.
This statement is not true. Electrons in the 4d subshell spend less time within the filled shells than does indium's one electron in the 5p subshell. Electrons with lower l values have more elliptical orbits. In this case, the electron in the 5p shell is at higher energy from its quantum number and from being alone in the outermost shell. This makes it easier to ionize.
