After reviewing the information in Figures 1 and 2 and the table
in the introduction, two students offer the following
hypotheses:
Student X: The number of fluorine atoms that bond to a metal
atom is equal to the number of valence electrons of the metal. The
number of fluorine atoms that bond to a nonmetal atom is equal to 8
minus the number of valence electrons of the nonmetal.
Student Y: In general, there is an inverse relationship between
the...
