Template:Chem/doc

This template allows you to render chemical formulas using HTML. Alternatively, you can use , using mhchem LaTeX notation to generate formulas.

Template instructions
This template, chem, serves to simplify the writing of chemical formulas. For example,

will yield:

Algebraic expression as subscript
Algebraic expressions are rendered as subscripts (but must not contain upper case letters). gives

Charge
Ion charge superscripts (for: +/-) are also supported:

yields a "+" as superscript:

Simultaneous subscripts/superscripts are automatically handled (use a hyphen for the minus sign):

gives "2−" as superscript:

The hyphen is converted to a true minus sign.

Atomic number and mass number
The first parameter can be used for mass number.

gives:

The first two parameters can be used for mass number and atomic number.

gives:

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. The Chem2 template can be used for e.g. ^{1}H2^{16}O, heavy water.

Linking
The optional parameter link changes the formula into a link. For example:

will yield:

Individual elements can be linked in the following manner: gives
