<P> The nonmetal binary fluorides are volatile compounds . They show a great difference between period 2 and other fluorides . For instance , period 2 elements elements fluorides never exceed the octet in their atoms . ( Boron is an exception due to its specific position in the periodic table . ) Lower - period elements , however , may form hypervalent molecules , such as phosphorus pentafluoride or sulfur hexafluoride . The reactivity of such species varies greatly -- sulfur hexafluoride is inert , while chlorine trifluoride is extremely reactive -- but there are some trends based on periodic table locations . </P>
