Chemists deal with lots of strange-sounding materials like sodium, ytterbium, and potassium hexacyanoferrate(III), so they’ve occurred a system of symbols and also formulas to stand for these materials. The aspects of the routine table all have actually one- or two- letter symbols*. In some cases the prize obviously descends from the element’s name; to wit, the symbol because that oxygen is O, the symbol because that titanium is Ti, and also the symbol because that chlorine is Cl.
Some facets – specifically the aspects that have actually been known since antiquity – have symbols that perform not seem logically associated to your name. In this cases, the symbol usually refers to an older surname for the element, probably from Latin or Greek. For example, the symbol because that sodium, Na, comes from the Latin indigenous natrium. Words natrium has an even deeper, richer background among the alchemists and scholars of the old world, or so says Elementymology & elements Multidict, a many fascinating site if you’ve obtained a couple of minutes come spare. At any rate, in 1807, teacher Humphrey Davy isolated the metal and recognized it as a distinct element. Bucking centuries of tradition, sir Davy decided the steel ought to be called sodium, because that he isolated it from caustic soda (now recognized as lye or salt hydroxide).

So what around sodium hypobromite? sodium hypobromite is a link that has sodium, bromine, and oxygen. Bromine and also oxygen incorporate to type a group dubbed a polyatomic ion. Due to the fact that this team has an overall negative charge, that bonds quite conveniently with positively-charged salt ions.
Bromine is fairly versatile as much as bonding through oxygen goes; there room actually several polyatomic ion made that bromine and also oxygen. Lock are differentiated by the variety of oxygen atoms bonded come the bromine atom, and also by little variations in your names. Here are four compounds that have the right to be do from the same three elements, and also their names:NaBrO = sodium hypobromiteNaBrO2 = sodium bromiteNaBrO3 = sodium bromateNaBrO4 = sodium perbromate
If one isn’t too picky around capitalization, one might read NaBrO together “Na, bro”, an interpretation “No, close male associate (or possibly my organic brother), I do not great to hear a joke worrying sodium hypobromite.” of course, the person already indicated his disinterest in hearing a joke about sodium. Possibly this fellow simply isn’t in the mood because that chemistry-themed jokes. We’ve all had actually days like that.

*Some routine tables have three-letter symbols for the last couple of elements. This symbols represent temporary names. When the global Union of Pure and Applied Chemistry, or IUPAC, assigns permanent names to these elements, they will obtain a traditional one- or two-letter symbol come go along with their name.
