Template:Chem/doc

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

will yield:

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

gives

Charge
Ion charge superscripts are also supported:

yields:

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

gives:

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.

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

will yield:

For linking individual elements can be linked in the following manner. gives
