One of these elements has the highest value of electronegativity.
In the Deacon process, transition metal oxides are used as a catalyst to isolate the gaseous form of one of these elements. One of these elements has a roughly 50-50 split between its 79 and 81 isotopes' occurrence in nature. A compound with uranium and (*) 6 atoms of one of these elements is used in enriching uranium and the lightest member of this group was the first discovered to bond with xenon. This group is the only one to have elements that are all three states of matter at room temperature. One of these elements has the highest value of electronegativity. For 10 points, name this group of elements that are one electron short of a full valence shell and include bromine, fluorine, and chlorine.
