| − | The {{w|periodic table}} is a table used to arrange {{w|chemical elements}} according to their chemical and physical properties. This comic proposes "changes" to the periodic table that would be more pleasant aesthetically or make the periodic table look more regular. Some of these are (somewhat) practical changes to element abbreviations that could improve clarity in English, though changing documents to use different abbreviations would probably be more trouble than it's worth. However, other changes move elements around without taking into account that elements would stop being arranged by their properties. The periodic table would stop being useful after such changes unless said changes were meant to physically change the material properties of the elements, which would be impossible{{citation needed}}, although the comic plans to solve the problem with "free training" to their atomic behavior. The attitude is similar to impossible economic plans attempted with unpleasant results, possibly a current event.
| |
| − | | |
| − | Other modifications make up new elements or remove existing ones from the table, which would not be a reasonable decision given that the periodic table is supposed to include all existing elements, whether they make the table neater or they don't.

| − | ! Proposed change !! Explanation
| |
| − | |-
| |
| − | |Move helium over here. It fits nicely!||Helium is moved from the upper right corner to the second column next to hydrogen. However, the reason it is placed at the far-right Group 18 and not Group 2 is because it is a {{w|noble gas}}, rather than a reactive {{w|alkaline earth metal}}. You could say helium is in group 2 because it has two electrons in its outer shell, but normal periodic tables place it in group 18, the noble gases, with which it has far more in common. Hydrogen has similar problems being in group 1, as it's a non-metal and the elements below it are metals which don't have much in common with it chemically. There are periodic tables that show hydrogen floating above the periodic table for that reason.
| |
| − | Group 18 was not known at the time of the original table, which used I-VII (1-7) for the otherwise full-height columns, which turns out to reflect the number of free ('valence') electrons in their outer 'orbit', in one useful understanding of the atomic model. When added, the new final column was called either VIII (having a full outer shell) or Group 0 (having none free) and placed to the right of VII. It was thought that these Noble gases were thought to be unable to react with other elements, but xenon compounds were discovered in 1962, and many others have been discovered since then, that are formed by a process not as trivial as being spare-valences of one element 'keying' into valence-gaps of another.
| |
| − | | |
| − | From the fourth row downwards the inserted block of Transition Metals represent a larger electron shell with more positions for free electrons and those elements to the right would have more electrons than those above them, by this measure, but their physical properties are still best dictated and aligned by the complement to the valence (i.e. the gap-size). The current numbering system shows the outer-shell electrons accurately in the rows where the ten new columns are, but the upper rows of columns 13-18 have ten more (or sixteen more, for Helium) than is the case. Similarly, once lanthanides and actinides are considered, the group number and outer-shell count becomes disconnected again in the opposite way. But it still seems useful enough to currently label in this manner under current {{w|IUPAC}} guidance.

| − | |Elements in this corner are cool. Add more!|| TBD (to be determined). Elements in that corner, such as carbon, oxygen, phosphorous, and nitrogen, participate in covalent bonding and are the primary elements involved in biochemical reactions, which may be why they are considered cooler than other elements.
| |

| − | |Sp (Spite element)||Wedged between fluorine and neon. This is a reference to spite houses, houses jammed into a narrow space to block other construction, or spite fences, which are fences built to annoy neighbors.

| |
| − | |Merge these boring metals with titanium to make *tixanium*||Tixanium (Tx) replaces five metals, including titanium (Ti). This may be a reference to the term "UX" (user experience) being used instead of "UI" (user interface) as more of an umbrella term.
| |
| − | | |
| − | While titanium certainly has an impressive name, and is used in the aerospace industry and other high-performance applications, the others are hardly boring; manganese, for example, was part of the cover story for the top-secret {{w|Project Azorian}}.

| |
| − | Since I is already used for Iodine, it gets a new abbreviation Io, and Gadolinium is re-abbreviated to Gm to free up Gd.
| |
| − | | |
| − | Note that most of these changes will actually make the table less readable if one considers languages other than English. For example, in european languages, 'I' for iron will work for Irish and Dutch, while 'Fe' currently matches in French, Italian, Portuguese, and most of the languages in Spain.
| |
| − | | |
| − | This group of changes doesn't include antimony (Sb -- stibium), but that’s because it gets replaced by “carbon III” (see below).

| |
| − | |Replace the blander post-transition metals with new kinds of carbon||
| |
| − | * Indium (In) -> C II.

| |
| − | * Tellurium (Te) -> C IV.
| |
| − | * Thallium (Tl) -> C V.
| |
| − | * Bismuth (Bi) -> C VI.
| |
| − | Carbon can make four covalent bonds, which means it can form a huge range of chemicals, above all ones vital to life. The post-transition metals don't have this level of interest. If there were more chemicals like carbon, it could allow more exciting chemistry and perhaps new kinds of life.

| |
| − | |That W annoys me|| Tungsten: W (Wolfram) -> Tg.
| |
| − | | |
| − | Another element whose symbol doesn't match its English name. "Wolfram" is the name for tungsten in some languages and is derived from the mineral wolframite, which comes from the name "wolf rahm" in German (wolf soot).
| |
| − | | |
| − | Oddly, despite changing Latin and German abbreviations to English, Randall does not change the symbol for mercury (Hg from the Greek "hydrargyrum").

| − | ;3.4% of all elements are named after Ytterby, Sweden (pop. 3,000). Let's keep Yttrium, but rename the other 3 after bigger cities (Tokyium, Delhium, and Jakartium?) to be more fair.
| |
| − | Four elements -- yttrium (Y), ytterbium (Yb), terbium (Tb) and erbium (Er) -- are named after {{w|Ytterby}}, a Swedish village where they were discovered. Scandium (Sc), thulium (Tm), holmium (Ho) and gadolinium (Gd) were isolated from minerals found in the same quarry. Randall suggests naming 3 of them after some other major world cities, despite those cities having no connection to those elements.
| |
| − | * Terbium (Tb) -> Tokyium (Ty) - Tokyo
| |
| − | * Erbium (Er) -> Delhium (Dh) - Delhi
| |
| − | * Ytterbium (Yb) -> Jakartium (Jk) - Jakarta
| |
| − | Randal may be using using 2010 census data (2946); Ytterby mine is located on the island of Resarö, found under 0187TB103 in table [https://www.scb.se/en/finding-statistics/statistics-by-subject-area/environment/land-use/localities-and-urban-areas/pong/tables-and-graphs/localities-2020-population-land-area-population-density-per-locality/ MI0810], population 3212 (2020 census).

| − | Interestingly, [https://en.wikipedia.org/wiki/Isaac_Asimov Isaac Asimov] made essentially the same remark in his science essay ''The Multiplying Elements'', saying that it was a waste of element names that could have been used to honor great contributors to chemistry. One obvious candidate would be [https://en.wikipedia.org/wiki/Henry_Moseley Henry Moseley] (mentioned in another of Asimov's essays, ''The Nobel Prize That Wasn't'') who used early X-ray spectroscopy to resolve the confusion over rare earth elements, finally put the Periodic Table on a firm ground and conceived the idea of "Atomic Number".

| |
| − | |Inserting the lanthanides and actinides properly makes the table too wide. Triage is needed. Each element will be offered free training to help adjust to its new column.||Though the lanthanides and actinides typically are placed underneath the bottom of the table, they actually belong in the 6th and 7th rows of the table between the 2nd and 3rd columns, as they are numbered elements 57-70 and 89-102. This section of the table is typically excised to give the overall shape more appealing dimensions; including this section in the main table [https://sciencenotes.org/wp-content/uploads/2017/01/PeriodicTableExtended.png extends the length dramatically]. This proves rather unwieldy especially when referencing the table for the lower-numbered elements, which are generally more common, and/or elements far to the sides of the table, which are often more influential in chemical reactions. Randall recommends that a subset of these elements be placed in a new row at the bottom of the table (making them elements 93-110) and they will receive "training" to adjust to their new columns.

| − | The title text suggests discovering elements only in entire rows at once. Elements with more protons than 118 could be discovered in future by collisions in particle accelerators, but aren't likely to be discovered in an entire row at a time.
| |
| − | | |
| − | Changing the periodic table was also the topic of [[2214: Chemistry Nobel]], and the red-ink style of "aesthetic" revision over a complex and established diagram is highly reminiscent of [[1902: State Borders]].
