Template:List of oxidation states of the elements/datacheck
This wikipedia has two lists of oxidation states of the elements. One is used in the infoboxes, an other one in the List of the OS'es. Both value sets (two sets for each element) are listed on this page. Ideally, these two lists are the same. However, as of 2020 there are some differences. These are listed, with a diff code in the rightmost column. For example, it can say "+1, 0" marking the values that differ.
The check
To do: per element, try to eliminate the difference. In general, when challenged, sourced values can be added (to the other list). Code "b" says there is a difference in bolded (main OS) values. These too should be the same.
These are the status codes (difference):
- +1, +2: different values
- 0: 0-value differs
- b: bolding of a value differs
- ok: values are the same
These are the data pages to edit (these are the live pages):
- List: {{List of oxidation states of the elements}} -- live
- {{Infobox element}} data: {{Infobox element/symbol-to-oxidation-state}} -- live (H, full index).
In this table, the checking administration (last column in this table):
- diff status: {{List of oxidation states of the elements/datacheck/diff}} -- difference note (column)
Not checked:
- not: (+1): predicted values (see E104, Rf, and heavier)
- not: −1: links
- not: <ref>: references used
