This WikiProject banner template uses Module:WikiProject banner, a meta-template for easily creating and maintaining project banners. Please report any errors or feature requests to Module talk:WikiProject banner. Information or warnings about the template are below:

This project banner uses priority or importance assessments but does not define a valid assessment page. Please add the |ASSESSMENT_LINK= parameter to fix this problem.
This banner template includes a link to Portal:Chemistry, and the accompanying image is File:Papapishu-Lab-icon-6.svg. See the instructions on how to change this.
Automatic parameter checking is enabled. Create the tracking category to track invalid parameters.

Template documentation

This template is used on approximately 10,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This is the WikiProject banner template used by WikiProject Elements to keep track of articles within its scope. All articles are categorised into Category:WikiProject Elements articles.

Basic usage

Place this on the talk page of relevant articles:

{{WikiProject banner shell |class= |
{{WikiProject Elements |importance= }}
}}

Full usage

It is usual to remove any unused parameters from the template call.

{{WikiProject banner shell |blp= |class= |listas= |
{{WikiProject Elements |importance= |GA= |isotopes= |category= }}
}}

Parameters

importance – see #Importance assessment below.
category – set |category=no if, and only if, a banner is being used for demonstration or testing purposes, to prevent unnecessary or undesirable categorization. Otherwise, omit this parameter.

Notes and alerts

GA – set |GA=yes or any non-blank value other than "no", "n" or "0". The following message will be displayed: "This article has been listed as a good article under the good article criteria."

Task forces

isotopes – set |isotopes=yes if the article is supported by the Isotope Taskforce. This parameter populates the relevant subcategory of Category:chemical element isotope articles by quality based on the |class= parameter.

Deprecated parameters

listas – this parameter should be used with the banner shell template, not on individual project banners. Please see Template:WikiProject banner shell for details.

Importance assessment

This project uses the standard importance scale. Valid values are shown below.

Input (not case sensitive)	Importance	Category	Population

Mid	Mid	Category:Mid-importance chemical elements articles	125
Low	Low	Category:Low-importance chemical elements articles	430
NA	NA	Category:NA-importance chemical elements pages	9,601

TemplateData

This template identifies the article as being within scope of WikiProject Elements.
