What is Hydron?
[[Image:Hydron.svg|thumb|150px]] In [[chemistry]] a '''proton''' is a positively charged [[hydrogen]] [[ion]]. According to [[IUPAC]], the name '''hydron''' should be used for such a particle.<ref>{{cite journal | title = Names for hydrogen atoms, ions, and groups, and for reactions involving them (Recommendations 1988) | year = 1968 | volume = 60 | issue = 7 | pages = 1115–6 | journal = [[Pure Appl.

(So chemists use the term ''hydron'' because it covers all three hydrogen ion isotopes.) In 1923, [[Johannes Nicolaus Brønsted]] and [[Thomas Lowry]] used hydrons to describe [[acid]]s and [[Base (chemistry)|base]]s. They defined acids as proton donors and bases as proton acceptors. ==References== {{reflist}} {{chem-stub}} [[Category:Chemistry]] [[Category:Ions]]
