Template documentation[view] [edit] [history] [purge]

This is the meta template {{Infobox isotopes (meta)}} for the element isotopes-infoboxes (Category:Infobox element isotopes templates (119)). It replaced {{Infobox element isotopes}} (meta) 18 Mar 2023.

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

 |ps1   =! product symbol 

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

For all code and formatted input: when not recognised, the input is shows as-is (unedited).

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

Parameters |na=, |hl= can handle simple keyboard code input. This simplifies typing:

|na=trace, synth, |hl=stable, obs stable.

|na=synth_link will link → synth

decay mode (β⁻β⁻) by keyboard code

Decay modes |dm1–4= can be entered as keyboard code:

|dm1=b+b+ (instead of |dm1=β<sup>+</sup>β<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

α ← a, β ← b, γ ← g, ε ← e

Note: plain Latin letter e used in "e+" only. (No confusion with "ee" for εε/ee).

x⁺, x⁻ ← + − (superscript = inline)
- − – - (keyboard hyphen = minus)
A≠a: keep uppercase: SF ← SF (sf)

percentage abundance, decay mode formatting

Half-life time: usually {{val}} to format|hl={{val|12.3|e=4|u=Ey}}} →12.3×10⁴ Ey. Do not link the unit.
Percentage input |na=, |perc1, perc2, perc3, perc4=

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%".

To evade this rule, use {{val}}: |na={{val|0.9995|u=%}} (e.g., hydrogen)

Do not add uncertainties "(5)" or "±0.3"

add reference

USe dedicated reference parameters:
|ref-table=<ref>... in column header
|ref-nubase2020=yes/no adds {{NUBASE2020}} in column header
|ref= per isotope
|ref= per decay mode

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^[update], 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 (t_1/2)	mode	product

Standard atomic weight A_r°(Li)

[6.938, 6.997]^[8]
6.94±0.06 (abridged)^[4]
