AP Chemistry 1.8 A Explain the Relationship Between Trends in the Reactivity of Elements and Periodicity Questions

Explore AP Chemistry 1.8.A questions on valence electrons, periodic reactivity, typical ionic charges, Coulombic attraction, and formulas for ionic compounds.

Exam points

Explain how reaction rates depend on collision frequency, activation energy and molecular orientation.
Apply rate laws, concentration changes and catalysts to predict how reaction speed changes experimentally.

[Maximum number: 1]

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.

Based on the student's hypothesis, what should be the formula of the compound that forms between chlorine and fluorine?
