Formulas, charges, equations: Charges are enclosed in parentheses.

New page

{{documentation subpage}}{{Lua|Module:Chem2}}
{{COinS safe|n}}
'''{{tl|chem2}}''' (or {{tl|CHEM2}}) is a template used to format a [[chemical formula]] or [[Chemical equation|equation]].

[[#why-vert-bar|'''^''']] If the last character of the template input is <code><nowiki>}</nowiki></code>, MediaWiki will confuse it with the end-of-template tag <code><nowiki>}}</nowiki></code>. Adding a space between the two resolves this ambiguity. Other options include instead inserting <code><nowiki>{{null}}</nowiki></code> or <code><nowiki><nowiki/></nowiki></code>.

==Formulas, charges, equations==
Formulas (without charge) are just written:
* <code><nowiki>{{chem2|CH3(CH2)5CH3}}</nowiki></code> → {{chem2|CH3(CH2)5CH3}}
* <code><nowiki>{{chem2|Fe3S2(CO)9}}</nowiki></code> → {{chem2|Fe3S2(CO)9}}
* <code><nowiki>{{chem2|C_{''n''}H_{2''n''+2}|}}</nowiki></code> → {{chem2|C_{''n''}H_{2''n''+2}|}}

Charges are written inside parentheses:
* <code><nowiki>{{chem2|SO4(2-)}}</nowiki></code> → {{chem2|SO4(2-)}}
* <code><nowiki>{{chem2|S19(2+)}}</nowiki></code> → {{chem2|S19(2+)}}

Charges +1 and −1 can be written plain:
* <code><nowiki>{{chem2|Na+}}</nowiki></code> → {{chem2|Na+}}
* <code><nowiki>{{chem2|O2-}}</nowiki></code> → {{chem2|O2-}}
: equals <code><nowiki>{{chem2|O2(-)}}</nowiki></code>

Chemical equations:
* <code><nowiki>{{chem2|2 S + 3 O2 + 2 H2O -> 2 H2SO4}}</nowiki></code> → {{chem2|2 S + 3 O2 + 2 H2O -> 2 H2SO4}}
* <code><nowiki>{{chem2|2S + 3O2 + 2H2O -> 2H2SO4}}</nowiki></code> → {{chem2|2S + 3O2 + 2H2O -> 2H2SO4}}
The arrows can be written as <code>-></code> or just <code>→</code>. All characters (and unicode markup) are valid input except <code>\</code>, = (Mediawiki use it), <code>_</code> and <code>-</code> (endash etc.)
* <code><nowiki>{{chem2|2 H2_{(g)} + O2_{(g)} -> 2H2O_{(g)}|}}</nowiki></code> → {{chem2|2 H2_{(g)} + O2_{(g)} -> 2H2O_{(g)}|}}
* <code><nowiki>{{chem2|NH2RCHCO2H <-> NH3+RCHCO2-}}</nowiki></code> → {{chem2|NH2RCHCO2H <-> NH3+RCHCO2-}}

[[Hapticity]] and mu:
* <code><nowiki>{{chem2|W(CO)3(PiPr3)2(\h{2}H2)}}</nowiki></code> → {{chem2|W(CO)3(PiPr3)2(\h{2}H2)}}
* <code><nowiki>{{chem2|auto=yes|W(CO)3(PiPr3)2(\h{2}H2)}}</nowiki></code> → {{chem2|auto=yes|W(CO)3(PiPr3)2(\h{2}H2)}}

==Wikilinks==
===Whole formula link===
Link the whole formula with {{para|link|<wiki pagename>}}:
* {{#invoke:demoTemplate|chem2|link=Iron(III) chloride|FeCl3}}

Or use wikilink brackets in input like <code><nowiki>[[ammonia|NH3]]</nowiki></code>:
* {{#invoke:demoTemplate|chem2|3[[hydrogen|H2]] + 2[[nitrogen|N2]] <-> 2[[ammonia|NH3]]}}

===Link each element (C, Hg) and generic element code (R, X)===
:Use {{para|auto|yes}} to link each element symbol once, as well as some others such as {{chem2|auto=1|Ph}}
* {{#invoke:demoTemplate|chem2|auto=yes|CH3CH2CH3CBrFCIClCH3}}

===Link functional groups===
Some common '''groups''' are recognized and linked if you wikilink them using <code><nowiki>[[ ]]</nowiki></code>
* {{#invoke:demoTemplate|chem2|R\-[[COOH]]}}
* {{#invoke:demoTemplate|chem2|[[CH3]]C[[R]]2[[I]]}}
* In particular H2O links to [[water of crystallization]] in {{#invoke:demoTemplate|chem2|CuSO4 * 5 [[H2O]]}}, because a link to water is generally unnecessary.

You can link to any article even if chem2 is unaware of it:!-- same as |link=... then -->
* {{#invoke:demoTemplate|chem2|[[C6H5NH2]]}}

To change the default link:
* {{#invoke:demoTemplate|chem2|[[water|H2O]]}}

===All recognised symbols and codes===
{{cot |bg=#CEF2E0 |title=All link targets recognised by {{tlf|chem2}} (elements, general codes, functional groups)}}
{{div col}}
{{#invoke:chem2|_autodoc}}
{{div col end}}
{{cob}}
