Editing oxidation state data: sp

New page

Data for the oxidation state entry in each element's infobox '''and''' for the [[Oxidation_state#List_of_oxidation_states_of_the_elements|List_of_oxidation_states_of_the_elements]]. Data entries here affect at least two pages.

==Editing oxidation state data==
The oxidation state data appears in three sections:
# '''common''' values from a single standard reference: Greenwood, N. N., Earnshaw, A. (2012). ''Chemistry of the Elements''. Germany: Butterworth-Heinemann. Please see the {{slink|Wikipedia_talk:WikiProject_Elements/Archive_63|What_is_a_"main_oxidation_state"?}}. These values should not be changed without consensus on the [[WT:WikiProject_Elements|Elements Talk page]].
# '''notable''' values from experiments, with reliable sources
# '''predicted''' values from theory, with reliable sources.
Each section has one entry for each element in the periodic table.

Each entry has strict limits to allow text processing.
* Each element result in a string
* Each string oxidation-state-number values
** an '''oxidation-state-number''' eg "+3," starts with
*** a space or a newline, followed by
*** a [[Wikipedia:Manual_of_Style/Mathematics#Minus_sign|math minus sign]] (not a dash) OR
*** a plus OR
*** nothing
*** followed by number,
*** followed by comma (every entry including the last one),
** a '''referenced-oxidation-state-number''' is an oxidation-state-number followed by
*** a <nowiki><ref>...</ref></nowiki> tag,
*** a <nowiki><sup>?</sup></nowiki> tag, or
*** a <nowiki><sup>*</sup></nowiki> tag creating the following reference:
{{Greenwood&Earnshaw2nd|page=28}}

The common entries are oxidation-state-number values. Do not include 0 (zero) in the common set.

The notable and predicted entries are referenced-oxidation-state-number values. Do not include formatting.

== How to add references ==
=== Find the element ===
Most of the time you want the second place the element is listed, for example for Titanium is the second place you see e"Ti=...".

===If the ref has not been used before===
Add it as normal.

===If the reference already used in the element page or in [[Oxidation state#References|Oxidation state]]===
Make an exact character for character copy of the ref and include it with the new oxidiation state data.

====OR====

* Note the value of the <code>name=</code> parameter. If there is none, add one using "Author-year".

* In this template add a self-closing "reference reference" with an name like "Author-date",eg
::<code><nowiki>6,<ref name="Smith-2006"/></nowiki></code>
* Add the reference definition in two places
In the element page '''and''' in [[Oxidation state#References|Oxidation state]] add the "reference definition" as a [[Help:Footnotes#List-defined_references|List-defined_reference]]:
<pre><nowiki>
==References==
{{Reflist|refs=
<ref name="Smith-2006">content1</ref>
<ref name="Joe-1936">content2</ref>
}}</nowiki></pre>
===Check===
Open the element page and [[Oxidation state#References|Oxidation state]] references for red Cite Errors.

== Template usage ==
This data template is designed for two use cases,
# [[Template:Infobox element]]
# [[Template:List of oxidation states of the elements]]
===Parameters===
* '''os-formatter''': a template that accepts symbol, common, notable, and predicted parameters and produces formatted wikitext.
* '''symbol''': element to be selected from the data.

The main-space pages that use these templates should include a definition of the reference named "cn" which might look like
::<code><nowiki><ref name="cn">Oxidation state{{citation needed}}</ref></nowiki></code>

===Formatters===
See the doc pages of these templates for examples.
# {{tl|Element-symbol-to-oxidation-state-echo|echo}}: debug output, used by default
# {{tl|Element-symbol-to-oxidation-state-entry|entry}}: formats for {{tl|Infobox element}}
# {{tl|Element-symbol-to-oxidation-state-row|row}}: formats for one row of {{tl|List of oxidation states of the elements}}

==Example debug output==
The examples use the "echo" formatter and the calls look like <code><nowiki>{{Element-symbol-to-oxidation-state-data|symbol=C}}</nowiki></code>
===C===
{{Element-symbol-to-oxidation-state-data|symbol=C}}
===Fe===
{{Element-symbol-to-oxidation-state-data|symbol=Fe}}
===He===
{{Element-symbol-to-oxidation-state-data|symbol=He}}
===Sg===
{{Element-symbol-to-oxidation-state-data|symbol=Sg}}
