Some binary compounds that form between fluorine and various nonmetals are listed in the table above. A student examines the data in the table and poses the following hypothesis:
the number of F atoms that will bond to a nonmetal is always equal to 8 minus the number of valence electrons in the nonmetal atom.
a. Based on the student's hypothesis, what should be the formula of the compound that forms between chlorine and fluorine?
b. In an attempt to verify the hypothesis, the student researches the fluoride compounds of the other halogens and finds the formula CIF3. In the box below, draw a complete Lewis
electron-dot diagram for a molecule of CIF3.

In an attempt to resolve the existence of the CIF molecule with the hypothesis stated above, the student researches the compounds that form between halogens and fluorine,
and assembles the following list.

d. Based on concepts of atomic structure and periodicity, propose a modification to the student's previous hypothesis to account for the compounds that form between halogens
and fluorine.
