Wikipedia:WikiProject Elements/PTG

Welcome
 * Periodic Table Graphics (PTG) is a taskforce of WikiProject Elements (talk).
 * The taskforce aims to improve graphic and presentational aspects of the periodic table. It follows and shows scientific content.

Scope

 * The graphics, not the scientific content.
 * By theme (topic), like categories, blocks, or by editorial form (like 18- or 32-column)

Goals
Goals of the taskforce are to improve graphic presentation of the periodic table. This includes
 * Present scientific information appropriately and usefully. Considering Wikipedia is an encyclopedia.
 * Apply WP:ACCESSABILITY ('A11Y') guidelines, aims and principles.
 * Improve explanations, descriptions etc.

Tasks, Active

 * State of Matter (SOM, Jan 2021)
 * Current 2020 SoM coloring (=use font colors) has issues.
 * As of 2021-01-23, an Emergency Edit has been made to make SoM-fontcolors into black all. W3C Contrast checking failed too often (5/18 existing combinations!)
 * A new presentation form (like icons not colors) is considered.
 * See, has wider discussion, interesting
 * Last Update: 19:45, 26 January 2021 (UTC)


 * Group 3 (GR3, Jan 2021)
 * See : Group 3 effectuated since 2021-01-23 (Sc-Y-Lu-Lr).
 * Periodic_table_(32_columns,_micro)#Group_3_options - group 3 forms

Tasks, Future

 * Micro PT (MICRO)
 * Could be redesigned to be more useful (like using larger cells).
 * Also, as used in Infobox element, can be made more effective.


 * Crystals
 * In Periodic table (by crystal structure)
 * The legend setup could be better. Why not use iconic images instead of colors? -DePiep (talk) 23:53, 23 January 2021 (UTC)


 * Metalloid graduals
 * These four classes better have gradual colors (say, blue-to-yellow in 4 steps).
 * Periodic table (list of metalloid lists) -DePiep (talk) 00:28, 24 January 2021 (UTC)

File:Periodic Table Radioactivity.svg Color reassessment needed. -DePiep (talk) 22:19, 24 January 2021 (UTC)
 * Image half-lives

Tasks, Past

 * ... – 2021-01


 * Category colors (CAT)


 * As of Jan 2021, this Taskforce PTG was buzy to find better category-colors.
 * Current live colorset is "2020" (as of 31 Dec 2020), see WikiProject Elements/PTG/categories/2020 and Periodic table.
 * Moot as of Jan 17, 2021

Conventions

 * In PTG, hex color triplets are shown in lowercase: 3af8ee.
 * "Chemical categorisation" explicitly refers to the science. For example, the "2020 categorisation" scientifically re-introduced "Halogens" category. After this, the topic "Colors of categories" will follow.
 * Category names are not relevant. For example, former PTM Post-transition metals is in 2020: OM Other Metals. Does not effect color design.
 * Also, exact category memberlist not very important. Except maybe when checking for neigbours (bordering).
