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

Template instructions[সম্পাদনা কৰক]

This template, {{chem}}, serves to simplify the writing of chemical formulas. For example,

{{chem|H|2|O}}

will yield:

H
2
O

Algebraic expression as subscript[সম্পাদনা কৰক]

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

{{chem|C|''n''|H|2''n''&nbsp;+&nbsp;2}}

gives

C
n
H
2n + 2

Charge[সম্পাদনা কৰক]

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

{{chem|H|3|O|+}}

yields a "+" as superscript:

H
3
O+

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

{{chem|SO|4|2-}}

gives "2−" as superscript:

SO2−
4

The hyphen is converted to a true minus sign.

Atomic number and mass number[সম্পাদনা কৰক]

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:

4
2
He
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[সম্পাদনা কৰক]

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

{{chem|link=water|H|2|O}}

will yield:

H
2
O

Individual elements can be linked in the following manner:

{{chem|[[Hydrogen|H]]|2|[[Oxygen|O]]}} 

gives

H
2
O

Notes[সম্পাদনা কৰক]

  • To include "=" in the formula, use "&#61;" For example, "{{chem|CH|2|&#61;CH|2}}" yields CH
    2
    =CH
    2
    .
    • Or, don't use this template. For example, "CH<sub>2</sub>=CH<sub>2</sub>" yields CH2=CH2.
  • To include "≡" in the formula, use "&#8801;" For example, "{{chem|HC&#8801;CH}}" yields HC≡CH.
  • The template accepts up to twenty parameters in addition to link.
  • This template uses {{su}}.
