No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

The elements at the very end of the periodic table are somewhat tenuous as we know "elements" to be, as there has only ever been very VERY small amounts of this material produced, and the isotopes of those materials that ARE produced split apart almost immediately with insanely small half-lives, so it's not like there's any amount of it just kicking around in a jar somewhere in some lab.
There's a ton of interesting reading on the theoretical island of stability in superheavy elements, where a special number of neutrons added to the isotope can possibly make these superheavy elements stable for a macroscopic amount of time so they could actually be studied and handled instead of instantly exploding apart and only being detected through their decay products.
https://en.wikipedia.org/wiki/Island_of_stability
I think there are elements with experiments designed to produce them up to around atomic number 125 or 127. Currently the highest confirmed, named, and somewhat categorized is 118. There's info out there about the theoretical elements. Here's the page for element 119. https://en.wikipedia.org/wiki/Ununennium. Purely theoretically, you could just keep adding rows to the periodic table, and it will keep going, but most of those materials will never actually exist or never could exist. It's kind of like theoretical vs applied math.

It contains the periodic table and all the unstable isotopes of every element. The island of stability would be somewhere in the top right corner, outside the chart.
When you look at the half-life data, it’s pretty clear that lead is the last fully stable element. Anything past that line (126 neutrons) is more or less unstable, but not necessarily useless. For example, uranium and thorium are pretty far away, but they can still have practical applications.
Between hydrogen and lead, stable isotopes are abundant, but after lead, finding anything you can reasonably do chemistry with gets a bit scarce. When you go past plutonium 244, you’ll find even less chemistry there.
When you say macroscopic time are we talking about seconds or years? Wondering whether we can actually build a circuit or something if we could produce a few mg of it.
It depends on which theorist you talk to. Some say seconds to minutes, others say days to weeks, the nutcases say thousands to millions of years.
And at the end of the day, the electrical properties of these elements probably aren't that interesting or useful, and almost certainly won't be like, semiconductors or anything fun. Just dumb, heavy, really fucking radioactive wire lol.
As long as it could be thousands of years we can dream about fantastic new elements that could make arc reactors or interstellar travel possible.
The more likely reality is a boring line of research of interest only to scientists
