- Or something else. From the beginning, what are the ten radical isotopes? -- Hkmaly (talk) 21:36, 12 October 2019 (UTC)
Couldn't this potentially involve exotic isotopes of hydrogen that behave similarly to elements in the same group? --220.127.116.11 16:02, 12 October 2019 (UTC)
Oh gods, I needed this laugh. Have my Chemistry exam on Monday, this does put a smile on my face.
"misconception that the empty space at the top of the periodic table represents undiscovered elements"... . Is that really a thing? Never heard of it. Ralfoide (talk) 16:53, 12 October 2019 (UTC)
- Somehow I did not think about that the entire time I was editing this thing, because I don’t believe it is. I guess I’ll fix it. 18.104.22.168 18:32, 12 October 2019 (UTC)
Some uninvited pedantry (unlike all my other didactic discourse here, which you guys bring on yourselves): Referenced in the comic is not THE periodic table, just a periodic table. And it isn't really objectively scientific. It's better to call it the most popular periodic table. Such tables are a rather ham-handed attempt to explain the patterns of the elements in an "intuitive" (or at least heuristic) way. But the popular one we learn in school is actually far from the best one even in that sense. Check out the alternatives, many of which are more scientifically sound and logical...but aren't as simplistic for the easy-minded, so they haven't caught on. —Kazvorpal (talk) 23:37, 12 October 2019 (UTC)
- Do you mean the one that looks like a candyland board game (Benfey's) or the one that looks like the worst Tetris level ever (Tsimmerman's)? [j/k]... If I had seen that in school, I'd have been too distracted to ever pay attention ;-) Ralfoide (talk) 07:35, 13 October 2019 (UTC)
- A very interesting link. Thanks! Yosei (talk) 12:41, 2 December 2019 (UTC)
Did Mendeleev really design his table to represent the way electrons are arranged in atoms? In 1869, he must have been quite a visionary! Zetfr 09:23, 13 October 2019 (UTC)
- Oh no, he didn't. He did by patterns of their properties. Also by atomic weights, but those were imprecisely known then, also note the isotope paradox problem (e.g. K and Ar must be swapped). The first sorting already guarantess to represent the electronic arrangement to some degree. BTW, lanthanides and actinides need more love. For starters, I PhD'ed on them.
- Actually he was quite the visionary, considering what they didn't know back then. While everybody else was arranging their tables (and there were plenty of them) entirely by atomic weight, he arranged them by both atomic weight on the large scale and chemical valence on the small scale. This clued him in to the changing periods and also enabled him to correct elements out of order by weight. The noble gases hadn't been discovered yet, but when they were, they fit right in as they had a valence of zero. A few decades later Henry Mosely used proton bombardment and X-Ray radiation measurement to determine the electrostatic properties of various elements and found a simple progression that both absolutely vindicated Mendeleev and introduced the concept of Atomic Number. He should have gotten a Nobel prize, but sadly, no prizes were awarded that year because of the war and Mosely himself was killed at the young age of 27 by a bullet with his name on it. Sigh.

Clearly these new elements are fractional elements, with elements having - for instance - 1 3/16 protons, etc. 126.96.36.199 21:20, 13 October 2019 (UTC)
Of course, if someone did find a whole bunch of elements there, I'd say that they deserve a Nobel prize. 188.8.131.52 12:37, 14 October 2019 (UTC)
for me, the explanation provided doesn't seem to emphasize why the joke works well enough. shouldn't the explanation more clearly state that the gap between hydrogen and helium is there because the table is grouped based on blocks of elements and electron orbits. the first row only has electrons in the s orbital and none in p, d or f orbitals, and that gaps between hydrogen and helium, for example, could not possibly be filled because there isn’t anything to fill them with. similarly for the 2nd and 3rd row "gaps". this impossibility really begets the humor of a figure pointing at the gap musing "i don't know why no one else thought to look here".
