Aether coudn't be in periodic table, just because Mendeleev discovered a today well-known pattern in "atomic and chemical properties of elements". Aether was never studied on the atomic and chemical properties.
Mendeleev wrote a big article about aether only in 1905, where he tried to find its place in periodic table for the first time, in response to multiple questions about aether place from other scientists, but went to conclusion that it is out of its scope, until aether atomic and chemical properties will be discovered and studied. He even tried to estimate aether properties it should have to fit into the table, and estimated aether "atom"(particle) mass as 9.6e-7 to 5.3e-11 atomic mass units ( 0.9Kev - 0.05 eV) constantly moving with a speed of 2250 km/s. This particles does not interact with matter or do that very rare. For me, this looks more like some low-energy neutrinos - light neutral leptons that rarely interact with usual matter. Who knows, may be there could be kind of matter (gas/liquid/solid) made from neutrinos created in quantities allowing studying physical and chemical properties of this substance, and only then we will be able to talk about placing "zero" element in periodic table, Pretty interesting task and research, but nobody tried to do that yet. At least I don't know about such attempts among existing researches on creating exotic matters of different kind.
There was no aether in periodic table, so there was nothing to remove in 1908. Mendeleev wrote an article on aether only in 1905, and didn't find a place for it in his table, because aether didn't have known physical and chemical properties at the time. Since scientists who was very interested in aether theory want to have aether as element, they tried to place it in a table of elements, so there could be some third-party unofficial periodic tables printed with aether in it somewhere, but they was just counterfeits of original one.
Aether problem is very interesting thing, actually, regardless of how it named in some timeframe - "dark matter", "higgs field", "fluctuating vacuum" and other stuff. Why there is a need to lie about it? There was no aether in periodic table, so nobody removed it. This does not mean anything about aether. I see a lot of narratives circulating about aether in conspiracy theorist circles, but never saw anything about studying it with modern technologies. Nobody from that circles talk about chemical properties of aether f.e. So why it should be in periodic table in the first place? It's just doesn't have any sense. Everything about aether today is as senseless as all that Nikola Tesla stuff, torsion fields stuff, and so on. Only talks and shitty memes based on lies. Why aether need that lies? What those who spread lies about aether and its position in science want to achieve with this lies? Marginalise it even more, or feed the sheeple who are LARPing conspiracy theorists?
