Template:Infobox element isotopes/doc

This is the element-specific Infobox for isotope-articles. It contains a table of main isotopes and evewntually the standard atomic weight. This template is reused in {{Infobox <element>}} as a child Infobox ({{para|child|yes]}).

As of Jan 2023, a 'Main isotope' is conforming MOS:MAINISOTOPE (under construction, see WP:ELEMENTS What is a "Main_isotope"?) When adding a new isotope to the list, use |main= to describe the reason for inclusion. For example: |main=medicine, nuclear power, dating, stable (only stable is obvious by itself). Like one would add as editsummary.

Each indvidual isotope has its own subtemplate, depending on its decay:

{{Infobox element isotopes
|symbol    =
|footnote  =
|isobox ref=
|isotopes  =
{{Infobox element isotopes/isotopes stable |mn= |sym= |link |hl= |main= |ref= }}
{{Infobox element isotopes/isotopes decay1 |mn= |sym= |link |hl= |main= |ref= |dm1= |pn1= |ps1= |link1                   }}
{{Infobox element isotopes/isotopes decay2 |mn= |sym= |link |hl= |main= |ref= |dm1= |pn1= |ps1= |link1 |dm2= |pn2= |ps2= }}
{{Infobox element isotopes/isotopes decay3 |mn= |sym= |link |hl= |main= |ref= |dm1= |pn1= |ps1= |link1 | .. 2 .. 3       }}
{{Infobox element isotopes/isotopes decay4 |mn= |sym= |link |hl= |main= |ref= |dm1= |pn1= |ps1= |link1 | .. 2 .. 3 .. 4  }}
}}

For single decay, unnumbered version is available:

{{Infobox element isotopes/isotopes decay  |mn= |sym= |hl= |dm= |pn= |ps= |link1 |main= |ref=}}

• The meta template is {{Infobox element isotopes}} (talk).

Table used in {{Infobox element}}

Parameters

Automated data: title, columnheaders, standard atomic weight. Isotopes are to be entered by the editor in |isotopes=, using one subtemplate for each isotope. The subtemplate produces one row in the table (possibly with multiple decay mode routes). The infobox adds the outer table form.

Notes:

• NUBASE2020: In general, referring to {{NUBASE2020}} is not needed, as this is the default referencing for isotopes.
• By specific decay mode: When the reference refers to a specific decay mode (α, SF), it can be added as opening text: |ref=SF decay: {{cite web}}
• No edits required: but in the long term it is advisable to move references from in-parameter into this one (for example, remove from |hl=2 y<ref>...</ref> to |ref=<ref>...</ref>).

Standard atomic weight

For stable elements, the formal standard atomic weight (s.a.w.) is added, as published by CIAAW. When the s.a.w. is in interval-notation, its conventional value is added too. Data is retrieved from central s.a.w. values lists, formatting is by {{Infobox element/standard atomic weight format}} (same as {{infobox element}}).
