:Not counting any posts made before the vale and/or veil of fire. [[Special:Contributions/150.221.155.241|150.221.155.241]] 22:10, 8 May 2026 (UTC)<br />
Why is it "vale of fire" instead of "veil of fire"? [[Special:Contributions/174.20.245.60|174.20.245.60]] 18:06, 8 May 2026 (UTC)<br />
:"vale" is a poetic term for a valley. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 19:06, 8 May 2026 (UTC)<br />
:: That is indeed the definition, but seems less appropriate than "veil" which has the connotation of blocking/obscuring.[[Special:Contributions/174.20.245.60|174.20.245.60]] 20:59, 8 May 2026 (UTC)<br />
::Not just a poetic term, but used in placenames (e.g. the "Vale of Evesham"), a vale generally more being a ''wide'' valley/flood-plain, framed by hills, rather than a 'mere' river-cut. But one of the more figurative/poetic terms I hear used is "vale of tears", a particularly sorrowful episode of life.<br />
::(PPE: a 'veil' and a 'vale' of obscuration would each be rather different concepts. Veil is a thin barrier, vale a 'territory' of (iin this case) inpenetrability. I think the chosen wor is as good a term, if not better, than the other... But, I don't know if it's an intentional choice or merely a slipup that fortunately landed on a somewhat-synonymic term.)

==Explanation==<br />
{{incomplete|This page was created APERIODICALLY. Don't remove this notice too soon.}}<br />
The {{w|Periodic Table of the Elements}} is a diagram often used to show the properties of the elements that make up the world. Its structure represents several properties of the elements- for example, all elements in a single column will have similar chemical properties, and increase in size going top to bottom. Elements in a given row decrease in size going left to right, with only a few exceptions, and there are similar trends in their tendency to gain or lose electrons, and other properties. Elements in a given row increase in the charge of their nuclei going left to right, but that's essentially by definition: they're ordered by atomic number, which is the same as their nuclear charge.<br />
<br />
Randall spoofs this concept by creating a similar diagram that is much less useful. The original table is "periodic" because it has consistent, repeating patterns that are represented by the horizontal position of the elements. Randall's table is "aperiodic", meaning it has no consistent, repeating patterns. Instead, it is just a line in order by {{w|atomic number}}. To fit in the same space as a normal periodic table, the sequence snakes back and forth and down the page in a space-filling manner. The diagram is not actually helpful, since it contains next-to-no information other than the atomic number of each element, plus faint colouring on each box to show its category, though due to the dull colours that is also quite inconvenient to use, and it depicts this information in an unnecessarily unhelpful and hard-to-read format.<br />
<br />
Chemistry and the periodic table is a periodic theme on xkcd, with there being many comics featuring humorous variations and "fixes" of it, such as [[2639: Periodic Table Changes]] and [[2975: Classical Periodic Table]].<br />
<br />
The title text might be a reference to [[3052: Archive Request]], or maybe some real attempts at inventing actual 'non-grid' linear versions of the periodic table, such as the {{w|File:Elementspiral_(polyatomic).svg|'periodic snail'}} that was created by {{w|Otto Theodor Benfey}}. It is also likely joking by relating scientists to zoo animals, from the reference to not having enough enrichment in their enclosures.<br />
<br />
Thallium’s symbol is incorrectly given as Ti in this comic; its actual symbol is Tl.<br />

[Rectangles showing the atomic symbols and atomic numbers from H 1 through Og 118 are arranged in a serpentine chain. The color of each rectangle matches the the pattern of a standard periodic table. For example, the noble elements all have a red background.]<br />
