Editing Boron group (section)

====Halides====
The elements in group 13 are also capable of forming stable compounds with the [[halogens]], usually with the formula MX<sub>3</sub> (where M is a boron-group element and X is a halogen.)<ref>[[#Henderson|Henderson]], p. 60</ref> [[Fluorine]], the first halogen, is able to form stable compounds with every element that has been tested (except [[neon]] and [[helium]]),<ref>{{cite journal|last1=Young|first1=J.

It is even hypothesized that nihonium could form a compound with fluorine, NhF<sub>3</sub>, before spontaneously decaying due to nihonium's radioactivity. [[Chlorine]] also forms stable compounds with all of the elements in the boron group, including thallium, and is hypothesized to react with nihonium. All of the elements will react with [[bromine]] under the right conditions, as with the other halogens but less vigorously than either chlorine or fluorine. [[Iodine]] will react with all natural elements in the periodic table except for the noble gases, and is notable for its explosive reaction with aluminium to form AlI<sub>3</sub>.<ref>{{cite journal|last=Francis |first=William |title=The Chemical Gazette, or Journal of Practical Chemistry |volume=XVI |page=269 |year=1918 |url=https://books.google.com/books?id=-KwRAAAAYAAJ&pg=PA269|location=Boston, Ma}}</ref> [[Astatine]], the fifth halogen, has only formed a few compounds, due to its radioactivity and short half-life, and no reports of a compound with an At–Al, –Ga, –In, –Tl, or –Nh bond have been seen, although scientists think that it should form salts with metals.<ref>{{cite book |title=The Halogen Elements: Fluorine, Chlorine, Bromine, Iodine, Astatine |last=Roza |first=Greg|year=2010 |publisher=The Rozen Publishing Group, Inc. |location=NY, New York, USA |isbn=978-1-4358-3556-6 |page=33 |url=https://books.google.com/books?id=twdXz1jfVOsC}}</ref> [[Tennessine]], the sixth and final member of group 17, may also form compounds with the elements in the boron group; however, because Tennessine is purely synthetic and thus must be created artificially, its chemistry has not been investigated, and any compounds would likely decay nearly instantly after formation due to its extreme radioactivity.<!--At-B bond is known, read astatine. At-F is still controversial, although tried. Uut hypothesis is uncited, literature talks even about UutF5. Also thought iodine doesn't react with sulfur-->
