This page uses the meta infobox ((Infobox isotopes (meta))) for the element isotopes infobox.

This infobox contains the table of § Main isotopes, and the § Standard atomic weight. For example, ((Infobox uranium isotopes)), as used on page Isotopes of uranium.

The main isotopes table is reused in the regular Infobox: ((Infobox uranium)).

Main isotopes table

((Isotopes/main/table/doc))

The Main isotopes table is build by entering one template for each isotope-row. 

((Infobox isotopes (meta)
...
|isotopes =
((Isotopes/main/isotope |link= |mn= |sym=
 |na= |hl=
 |ref=
 |dm1= |perc1= |ref1= |link1= |pn1= |ps1= 
 |dm2= |perc2= |ref2= |link2= |pn2= |ps2=
 ))
...
))

 The single-row parameters, commented
 "!"=could be required;
  ..1&ndash;4 refer to the decay mode dm#=
((Isotopes/main/isotope
 |mn    =! massnumber
 |sym   =! symbol
 |link  =  isotope page: uranium-232
 |ref   =  reference for the isotope-row
 |na    =! natural abundancy (can be: synth, trace)
 |hl    =! half-life (can be: stable)

 |dm1   =! decay mode #1
 |perc1 =  % decay
 |ref1  =  reference for decay mode #1
 |link1 =  product isotope page
 |pn1   =! product mass number
 |ps1   =! product symbol 

 |dm2   =  decay mode #2 etc.
 |dm3   =  decay mode #3 etc.
 |dm4   =  decay mode #4 etc.
 ))

abundance, half-life trace, synthetic, stable by keyboard code

|na=trace, synth, |hl=stable, obs stable.
|na=synth_link will link → synth
See also: percentage abundance, below.
When not recognised, the input is shows as-is (unedited).

decay mode (β−β−) by keyboard code

|dm1=b+b+ (instead of |dm1=&beta;<sup>+</sup>&beta;<sup>+</sup>), will show β+β+.
Also, to wikilink:
|dm1=b+b+_link → β+β+.
When not recognised, the input is shows as-is (unedited).
basic dm1–4 code rules
Note: plain Latin letter e used in "e+" only. (No confusion with "ee" for εε/ee).

percentage abundance, decay mode formatting

No need for ((val)), plain "12.34%" will do.
The number willbe rounded to 3 sigfig.
When dm-% |perc1=0.003%, then formatted as "<0.01%".
When dm-% |perc1=2.7e-12, then formatted as "≪0.01%".
Do not add uncertainties "(5)" or "±0.3"

add reference

Do not add reference with input value: dm1=α<ref>..</ref>

Standard atomic weight

The Infobox contains the table of Main Isotopes (more below), and the standard atomic weight (as published by CIAAW, see ((Infobox element/symbol-to-saw/CIAAW-saw-element-page)).

what's new

Mar 2023
Main usually refers to Main isotopes (not mainspace, not main-article about ..)

usage

This is the Infobox for an elements main isotopes. The meta-templatee is ((Infobox isotopes (meta))) (META)

It contains a table of main isotopes and eventually the standard atomic weight.

This template is reused in ((Infobox <element>)) as a child Infobox (|child=yes).

As of Jan 2023, a 'Main isotope' is conforming MOS:MAINISOTOPE (under construction, see WP:ELEMENTS What is a "Main_isotope"?)

Each isotope has its own row, with decay modes:

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))). Example:

Isotopes of lithium (3Li)
Main isotopes Decay
abun­dance half-life (t1/2) mode pro­duct
Standard atomic weight Ar°(Li)
((Infobox isotopes (meta)
|symbol=Li
))
