Knowra Interhalogen compound Interhalogen compound An interhalogen compound contains atoms of two or more different halogen elements. Most are molecular compounds in which one halogen is bonded to another.
Halogen : An element in Group 17 of the periodic table, including fluorine, chlorine, bromine, iodine, and astatine. Interhalogen compounds form by combining different members of this element group.
Interhalogen molecular geometry : The three-dimensional arrangement of atoms in molecules containing different halogens. AX, AX3, AX5, and AX7 formulas correspond to distinct molecular shapes.
Chlorine trifluoride : A reactive interhalogen compound with the formula ClF3. Its T-shaped molecule exemplifies the AX3 family and its strong oxidizing behavior.
Uranium hexafluoride : A volatile uranium compound used in uranium isotope separation and nuclear-fuel processing. Fluorine chemistry involving interhalogens can support routes to uranium fluorides.
Hydrogen halide : A binary compound containing hydrogen bonded to a halogen. Hydrogen halides contain hydrogen, whereas interhalogens contain only halogen elements.
Electronegativity : A measure of an atom's tendency to attract shared electrons in a chemical bond. Differences between halogen electronegativities shape bond polarity and chemical reactivity.
Interhalogen reactivity : The chemical behavior of compounds formed from different halogen elements. Polar bonds and reactive halogen atoms make many interhalogens effective halogenating agents.
Iodine heptafluoride : An interhalogen compound with the formula IF7 and a pentagonal-bipyramidal molecular shape. It is a stable example of the rare AX7 structural family.
Nuclear fuel cycle : The sequence of processes that supplies, uses, and manages nuclear fuel. Specialized fluorinating reagents connect interhalogen chemistry with fuel-material processing.
Polyhalide : An ionic species containing a polyatomic assembly of halogen atoms and carrying an overall charge. Polyhalides are charged ions, unlike the usual neutral molecular interhalogens.
