Template instructions
This template, {{chem}}, serves to simplify the writing of chemical formulae. For example,
{{chem|H|2|O}}
will yield:
- H 2O
Algebraic expression as subscript
Algebraic expressions are rendered as subscripts (but must not contain upper case letters).
{{chem|C|''n''|H|2''n'' + 2}}
gives
- C nH 2n + 2
Charge
Ion charge superscripts (for: +/-) are also supported:
{{chem|H|3|O|+}}
yields a "+" as superscript:
- H 3O+
Simultaneous subscripts/superscripts are automatically handled (use a hyphen for the minus sign):
{{chem|SO|4|2-}}
gives "2-" as superscript:
- SO2−4
- Note
- The hyphen is converted to a true minus sign.
Atomic number and mass number
The first parameter can be used for mass number.
{{chem|4|He}}
gives:
- 4 He
The first two parameters can be used for mass number and atomic number.
{{chem|4|2|He}}
gives:
- 42He
- Note
- Only the first two parameters can handle two consecutive plain numbers (i.e. without a plus sign or a hyphen (
+
or-
) following). Otherwise the template will loop.
Linking
The optional parameter link changes the formula into a link. For example:
{{chem|link=water|H|2|O}}
will yield:
For linking individual elements can be linked in the following manner.
{{chem|[[Hydrogen|H]]|2|[[Oxygen|O]]}}
gives
Notes
- To include "=" in the formula, use
=
For example,{{chem|CH|2|=CH|2}}
yields CH 2=CH 2.- Or,
{{chem|CH|2}}={{chem|CH|2}}
, which yields CH 2=CH 2. - Or, don't use this template. For example,
CH<sub>2</sub>=CH<sub>2</sub>
yields CH2=CH2.
- Or,
- To include "≡" in the formula, use "≡" For example, "{{chem|HC≡CH}}" yields HC≡CH.
- The template accepts up to twenty-four parameters in addition to
link
. - This template uses {{su}}.
TemplateData
Encodes a chemical formula. This template make use of overloading so it cannot be easily documented for VisualEditor. Each parameter can be a chemical element symbol like 'Si'; a number or algebraic expressions (2''n'' + 2) – rendered as subscripts; charges '+', '-', '2+' etc. – rendered as superscripts. Additionally the first parameters can be mass number and atomic weight.
