Talk:List of chemical elements

This article is written in British English with Oxford and IUPAC spelling (colour, realize, organization, analyse; note that -ize is used instead of -ise; aluminium, sulfur and caesium) and some terms that are used in it may be different or absent from other varieties of English. According to the relevant style guide and chemistry naming conventions, this should not be changed without broad consensus.

Hydrogen peroxide

Regarding the density of plutonium. Allotropes_of_plutonium says 19.86 for alpha phase, but there are six phases. Phases can be stabilized by alloying with a small amount of something else, and commonly are. The table doesn't mention phase at all. It seems that bomb plutonium, presumably where much of it is, is stabilized in delta with a small amount of gallium. Gah4 (talk) 21:01, 28 September 2020 (UTC)[reply]

I have changed the List of elements into using dedicated table {{List of chemical elements}} (/doc)

In short

The table is build with row-subtemplate for each element to ease handling input, formatting, changes. Some data is read from central data lists (such as standard atomic weight). Some repetitive footnotes, for example on full sets of elements, are removed. Basic numerical handling in formatting and sorting.

In detail

Columns

Added columns block, origin, phase

Add separate parameter for symbol clarification (like "Hg")

Anchor by symbol added for cross-linking: #He (for example List of chemical elements § Y for the Ytterby brothers)

Data sources

Use standard-data from Category:Element data sets (0) when available.

Per symbol: name, Z, group, period, block, s.a.w., origin, phase

Otherwise, data from old version was used initially

For: etymology, density, m.p., b.p., heat capacity, electonegativity, abundance

Etymology refined writing & punctuation, crosslinks added (e.g. between the four Yterbium-names)

Notation

Used "( )" when projected or estimated value

Format by {{val|gaps}}

Sorting uses numerical value ({{val}} feature)

Footnotes

removed footnotes referencing uncertainty

removed footnotes that describe sets of elements

kept footnotes on singular exceptions (He, As, Pu)

repeat footnote from header at first live appearance (e.g., first actual [ ] notation)

Compare old/new version

{{List of chemical elements/2020}}

Technical

use row-template, parameters

use {{val}} when "( )" value (needed for number handling)

Not done

Check existing data by source

No mayor changes

Right now at Chemical_element#List_of_the_118_known_chemical_elements there's a very useful feature: a short explanation of some of the headers. It's missing from List of chemical elements. And, it could be expanded to include most or all of the headers. It would be nice to have a more trim look for the headers. This would save some screen space, particularly on small screens. Some explanation could also be in the headers using {abbr} tags. I'll add both of these to the template itself if there are no objections.

As a side note, the name origins could probably be in {efn} tags to save even more space. Wizmut (talk) 06:10, 7 January 2025 (UTC)[reply]

I made some of these changes but did not include the explanations outside the table. These could be added to each place where the table appears, except in cases where such text would not be expected. Wizmut (talk) 20:57, 9 January 2025 (UTC)[reply]

Wouldn't it be useful to add a information about whether the element has stable isotope(s)? It not necessarily should be another column, it could be colour-coded for example. Pko (talk) 19:51, 21 June 2025 (UTC)[reply]
