(9 Pts) In one of the two Rare Earth element rows of the periodic table, identify an exception tothe general ionization energy (IE) trend. For the two elements involved, answer the followingquestions. Be sure to cite sources for all physical data that you use.a. (2 pts) Identify the two elements and write their electronic configurations.b. (2 pts) Based on their configurations, propose a reason for the IE trend exception.c. (5 pts) Calculate effective nuclear charges for the last electron in each element and theAllred-Rochow electronegativity values for the two elements. Can any of these valuesexplain the IE trend exception? Explain how (not) – include a description of how IErelates to electronegativity.

Question
(9 Pts) In one of the two Rare Earth element rows of the periodic table, identify an exception to
the general ionization energy (IE) trend. For the two elements involved, answer the following
questions. Be sure to cite sources for all physical data that you use.
a. (2 pts) Identify the two elements and write their electronic configurations.
b. (2 pts) Based on their configurations, propose a reason for the IE trend exception.
c. (5 pts) Calculate effective nuclear charges for the last electron in each element and the
Allred-Rochow electronegativity values for the two elements. Can any of these values
explain the IE trend exception? Explain how (not) – include a description of how IE
relates to electronegativity.
