- ^ Different sources give different values for half-lives; the most recently published values are listed.
The master template provides an {{ Isotopes summary}} table. It is designed to be used in element article sections, like Roentgenium#Isotopes.
Usage
This template is used in the articles for superheavy elements to produce the sortable lists of isotopes. It was created to simplify formatting and standardize references. For each isotope, a row {{ isotopes summary/isotope}} is to be added.
The template {{ notelist}} is required on any pages that use this template.
Parameters
Main template (table body)
{{Isotopes summary
|element =
|year_ref =
|reaction_ref=
|isotopes= <!-- tablerow subtemplates, see below -->
{{Isotopes summary/isotope
|mn=
|sym=
|hl=
|ref=
|dm=
|year=
|re=
}}<!-- repeat for each isotope -->
}}
| Parameter | Description | Notes |
|---|---|---|
|element=
|
The name of the element | in lowercase |
|year_ref=
|
Reference for the "Discovery year" column | No default |
|reaction_ref=
|
Reference for the "Discovery reaction" column | No default |
Isotopes parameter
Use {{ Isotopes summary/isotope}} to create one row for each isotope in the table.
|mn=
|sym=
|hl=
|ref=
|dm=
|year=
|re=
| Parameter | Description | Notes |
|---|---|---|
|mn=
|
Isotope mass number | |
|sym=
|
Element symbol | |
|hl=
|
Most recently published half-life. Values are from {{ NUBASE2016}} unless a paper published in 2015 or later gives a different value. |
Use {{
sort}} to assign sortable values. Do not include unknown isotopes. (i.e. those with no discovery year listed) |
|ref=
|
Reference for the half-life column. | Add as a footnote (<ref></ref>). |
|dm=
|
Decay modes | There can be multiple separated with commas. |
|year=
|
Discovery year | Citation already in table header. |
|re=
|
Synthesis reaction | Written the same as in normal tables or article text. Citation already in table header. |
Sample use
{{Isotopes summary
|element=tennessine
|year_ref=<ref name=nubase /> <!--not fully included here, but a normal citation-->
<!-- |reaction_ref= not included, so the default value is used -->
|isotopes= <!--add one sub-template for each isotope-->
{{isotopes summary/isotope
|mn=293
|sym=Ts
|ref=<ref name=shesummary /> <!--not fully included here, but a normal citation-->
|nubase={{sort|00021|21 ms}}
|dm=α
|year=2010
|re=<sup>249</sup>Bk(<sup>48</sup>Ca,4n)
}}
<!-- new template, new row-->
{{isotopes summary/isotope
|mn=294
|sym=Ts
|hl={{sort|00051|51 ms}}
|ref=<ref name=shesummary />
|dm=α
|year=2010
|re=<sup>249</sup>Bk(<sup>48</sup>Ca,3n)
}}
}}
produces the following:
| Isotope | Half-life [a] | Decay mode |
Discovery year [1] |
Discovery reaction | |
|---|---|---|---|---|---|
| Value | ref | ||||
| 293Ts | 22 ms | [2] | α | 2010 | 249Bk(48Ca,4n) |
| 294Ts | 51 ms | [2] | α | 2010 | 249Bk(48Ca,3n) |
