แม่แบบ:เคมี
หน้าตา
วิธีใช้แม่แบบ
[แก้]แม่แบบนี้ "{{chem}}" ทำให้การเขียนสูตรทางเคมีได้ง่ายขึ้น ตัวอย่างเช่น
{{chem|H|2|O}}
จะได้:
- H
2O
ใช้เป็นดัชนีล่างของนิพจน์พีชคณิต
[แก้]นิพจน์พีชคณิตที่ถูกแสดงเป็นดัชนีล่าง (แต่ห้ามมีตัวอักษรตัวพิมพ์ใหญ่)
{{chem|C|''n''|H|2''n'' + 2}}
จะได้:
- C
nH
2n + 2
Charge
[แก้]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
[แก้]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
2He
- 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
[แก้]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
[แก้]- 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,
- Or, don't use this template. For example,
CH<sub>2</sub>=CH<sub>2</sub>
yields CH2=CH2.
- Or, don't use this template. For example,
- 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}}.
