Talk:Polyatomic ion

message: Please help with the format of this table!!!
I'm working on moving the data into a table, shown below. - fagan
Some commonly-occurring polyatomic ions and their charges are
indicated below, ordered from most positive to most negative, and alphabetically for those with the same charge.
NameFormula
ammoniumNH4+
acetateCH3C(=O)O- also written as CH3COO- or C2H3O2-
OxideO4-2
CalciumCa4+2
LeadPb4+4
BariumBa4+2
LithiumLi4+
HydrogenH4+

I think the table REALLY needs to be split into another column...look at all that space that can be used, its to long, need another table continuing...--69.111.8.235 01:58, 27 November 2006 (UTC)

text: The nomenclature rule isn't about the charge or number of oxygens on the most common ion, rather the relative number of oxygens in those ions with fewer or more than the most common. Vsmith 02:19, 10 December 2006 (UTC)

text: Wouldn't it be better to just (create and) link to a category where all polyatomic ions can be collected? That way, we don't have to keep maintaining a large unwieldy table. There's already :Category:Oxycations, for example.—Tetracube (talk) 00:21, 12 March 2009 (UTC)
replies: text:  Some entries are odd- e.g. carbonite. As a first step to enhancing this article I would suggest that the list is thinned down to cover just familiar examples, headed ""Examples of some polyatomic ions"  and split (or separate list ) between cations and anions.--Axiosaurus (talk) 16:55, 27 March 2009 (UTC)
replies: text: Good idea, I'll work on trimming it down. Thanks for the suggestion.—Tetracube (talk) 17:00, 27 March 2009 (UTC)
thread_title:  Misc 

message: The article currently says:
[...] the term refers to small collections of atoms, 3 to perhaps 50 atoms, such as many metal complexes and oxyanions such as sulfate. in Greek, the prefix poly- means "many," which to a chemist means three or more atoms.
Is it not two or more atoms? Many of the ions in the table (like hydroxide which is also given as an initial example) have only two atoms. 217.116.235.64 18:36, 16 September 2007 (UTC)
thread_title:  Diatomic ion is not polyatomic? 

message: Is this really a good choice of words?
Although most polyatomic ions are pussies, (all electrons are paired), some are radicals.
I think this could be cleaned up a bit. 192.103.41.201 23:15, 3 October 2007 (UTC)
thread_title:  Wording 

message: There are a lot of polyatomic species out there (most of coordination chemistry, 99.999% biomolecules).  This list seems like the kind of good idea until you think about it.  Also I notice that the list includes ions that are not real in the usual physical world such as chromite (CrO2-), hypophosphite (PO2-). I dont have any ideas other than kill the table or put lots of disclaimers on it.  I guess one could say that the table does no harm, except to delude the reader into thinking that the number of ions is modest in number and that some species listed as ions dont exist outside of mass spectrometers.--Smokefoot (talk) 01:10, 9 December 2007 (UTC)

thread_title: Listing all polyatomic ions may be unrealistic and possibly ill-advised

message: The nomenclature section seems to deal only with anions. Cations do not follow this pattern (there is no discussion of the -yl suffix for cations, for example); somebody should expand this article with that.—Tetracube (talk) 17:30, 27 March 2009 (UTC)
thread_title:  Nomenclature section 

message: "External cheese links"??? I think it's supposed to say "External links"  — Preceding unsigned comment added by 24.15.117.78 (talk) 23:18, 10 November 2011 (UTC)
thread_title:  Um.... 

message: Regarding: First, think of the -ate ion as being the "base" name, I think that the use of the word "base" is confusing since when I first read this I thought that it was referring to "a base" as in acids and bases. I'm not sure what to suggest instead. Perhaps "root" or "nominal" instead of "base".
