Adamantium, bolognium, dilithium. Element Zero, Kryptonite. Mythril, Netherite, Orichalcum, Unobtanium. We love the idea of fictional elements with miraculous properties that science has yet to discover. But is it really possible that new elements exist beyond the periodic table?

@jensraab2902 Рік тому
Wow, that was a scarily bad teacher. They could have used your question to engage the class and go a little deeper. Throw the question back at everybody and see if anyone had a good idea. One of the obvious lessons would be that elements as we know them (made out of protons, neutrons and electrons*) are complete in the sense that there is no longer any gaps in the table, just room for even heavier elements. The next lesson could then be to get the class to realize that all the heaviest elements are unstable and that the half-lives are rather getting shorter, and potentially hint at how the heaviest elements are synthesized. They could have hinted at the possibility of hypothetical stable elements (or at least those whose half-lives are long enough to be around for a reasonably long time) even though synthesis is currently out of our reach. Even saying all of this in a two or three sentences would have been more productive than shutting you down with an argument from authority. * there are actually atom-like formations -so-called exotic atoms- where any of these is replaced by another particle but this might have been a little too-much off-topic cf. en.wikipedia.org/wiki/Exotic_atom

I would expect the next row of the periodic table to be even longer than the current ones. Every two rows, we see the addition of a new electron orbital (the rare earths actually fit in the table, but are dropped below it for display purposes). And with the next row, we're due for a fifth electron orbital type with 18 electrons.

@@Feyser1970 No, but they do determine how the element reacts. And electrons = protons in (non-ionic) atoms. The S orbital holds 2 electrons. That's Hydrogen & Helium, then the first two columns of the periodic table. Then the P orbital is next; it holds 6 electrons, which are the last 6 columns (Boron through Neon in the first row). Two rows later, we add the D orbital, which holds 10 electrons. That's the middle of the periodic table. Finally (for now), we add the F orbital two rows later which has 14 electrons. That's the rare earths. With the upcoming row, we're due for a fifth orbital with 18 electrons if the pattern continues

Unfortunately the answer is no. The recent hypothesis that heavy elements are made in neutron star collisions makes it clear that all possible superheavy elements would be created. If there were any stable ones we'd have found them in nature. Another possibility is forms of matter made of non-standard quarks, I don't believe that is ruled out.

Potential completion of the Periodic Table of the Elements: I currently believe that there are 120 chemical elements in this universe. If a person were to look at how electrons fill up the shells in atoms: 2, 8, 18, 32, 32, 18, 8 (seven shells), and realizing that energy could freely flow in this universe if nothing stopped it from doing so, then a natural bell shaped curve might occur. An eighth energy shell might exist with a maximum of two elements in it, chemical element #119 (8s1) and chemical element #120 (8s2). Chemical Element #119 (8s1): #119 I put at the bottom of the Hydrogen group on the Periodic Table of the Elements. It only has one electron in it's outer shell with room for only one more electron. Energy might even enter the atom through the missing electron spot and then at least some of the energy might get trapped inside of the atom under the atom's outer shell. Chemical Element #120 (8s2): #120 I put at the bottom of the Helium group since it's outer shell is full of electrons. It might have some of the properties of group two, Beryllium group (Alkali Earth Metals group) since it has two electrons in it's outer shell; as well as some of the properties of the Helium group (Noble Gases group) since it's outer shell is full of electrons; and if you look at the step down deflection of the semi-metals and where #120 would be located on the chart, it's possible #120 might even have some semi-metal characteristics. #120 would be the heaviest element in this universe. I believe chemical element #120 could possibly be found inside the center of stars. When a neutron split inside of this atom, it would give off one proton, one electron, neutrinos and energy. The proton and electron would be ejected outside of the atom since all their respective areas are full. One proton and one electron are basic hydrogen, of which the Sun is primarily made up of, and the Sun certainly gives off neutrinos and energy. And note, it's the neutron that split, not a proton. So even after the split, there are still 120 protons inside of the atom and the atom still exists as element #120. The star would last longer that way. In addition, if the neutron that split triggered a chain reaction inside of the star, this could possibly be how stars nova, (even if only periodically). If stars were looked at as if this theoretical idea were true, and found to even be somewhat true, then we might just have a better model of the universe to work with, even if it's not totally 100% true. And if it's all 100% true, then all the better.

I think I read somewhere that the island of stability is a moving frontier. A few years back, it was expected that elements above 115 or 116 would be found to be a bit more stable than the ones before, as they would be the "shore" of the island. Now that we are up to 118 with each new element being less and less stable, the island is predicted to be further away...
@garethdean6382 Рік тому
Yes. There's a few issues at play. One is that our knowledge is imperfect, there are several theories on where the island (Or in some places 'continent') will be, a few of which are now disproven. Our creation of heavy elements often informs us of more distant possibilities. (Or lack thereof.)
@davidguthary8147 Рік тому

@Lucius_Chiaraviglio Рік тому
Originally we were supposed to get an island of stability around element 114, but they just keep getting more unstable as we make heavier elements. The heavier elements seem to be caught in a squeeze in which those that do not have a high enough neutron to proton ratio alpha decay very rapidly, whereas those that have a higher neutron to proton ratio spontaneously fission (you see this first with fermium, of which isotope 257 is the most stable isotope, alpha decaying with a half-life of 100.5 days, and then isotope 258 spontaneously fissions in less than a millisecond (and note that the even-even rule of stability doesn't work here and for some other transuranium elements), and isotopes 259 and 260 also spontaneously fission very quickly. After fermium, you get a slight break with mendelevium, for which you can get the highest few isotopes to have enough neutrons that they can actually beta decay, but then starting with nobelium anything that doesn't alpha decay spontaneously fissions, and it gets faster until by the time you get to the upper end of what we have been able to make, you can't do anything with what you have made other than confirm detection. Current technology (ramming calcium 48 into a heavy element) should in principle get us to Element 121 -- in principle, it should be possible to make macroscopic quantities of einsteinium (actually, we already did that at least once, with einsteinium 253, half life 20.47 days, and that isn't even the most stable isotope), Fermium 257 (half-life 100.5 days), and mendelevium 260 (half life 27.8 days); adding 20 protons gets you Elements 119, 120, and 121, respectively. After that, you would have to use a heavier projectile (they're already trying titanium 50, with no success so far), but then you won't be able to get as high a neutron to proton ratio, so alpha decay instability will be even worse, and then you really won't be able to detect what you have made, let alone do anything with it.

Does gravity play a role in why heavier elements are unstable? Love your comment, you sound like a scientist.
@Lucius_Chiaraviglio 8 місяців тому
@@botezsimp5808 I am, although physics (including nuclear physics) isn't my specialty (but I do know how to look stuff up and read it). As far as is known, gravity plays no role (*)in the instability of heavier elements, but electromagnetism does: Protons repel each other because they are all positively charged, and their repulsion declines only with the square of the distance, because electromagnetism has no range limit; whereas protons and neutrons attract each other by way of the strong nuclear force, which starts out stronger but falls off faster than the square of the distance, so that as a nucleus gets bigger, the electromagnetic repulsion starts to catch up. Well before getting to the point at which the nucleus would simply fly apart, you get a situation in which the nucleus can become more strongly bound by rearranging itself into 2 (or sometimes more) smaller nuclei; in the case of rearranging into 2 moderate-sized nuclei, enough energy is left over from this to kick out a few neutrons (hence the possibility of fission chain reactions). (*)If it turns out that gravity and the other forces (including electromagnetism) unify, then gravity would play a role; however, at this point, it is not proven whether gravity is a real force in the sense of the other forces or simply the result of the mathematics of spacetime curvature caused by concentrated accumulations of mass/energy. Many scientists think that gravity is an actual force (as well as curving spacetime) that does unify with the other forces at extremely high energies, but have no way to test the hypothesis with current or foreseeable technology.

Przybylski's Star has an abundance of Actinides in it's spectra. Like, plutonium, americium, & einsteinium seem to be in it. These should not be present if that star is of any reasonable age. So, either they are from decay of super heavy elements inside that star, or, the light spectrum of this star is being misunderstood.

From my understanding stars can't fuse anything heavier than iron, they go supernova once iron begins to be produced in the core, since anything as heavy or heavier than iron takes more energy to fuse than it produces. Maybe the spectra emissions come from ionized material being absorbed into the star from surrounding space? Perhaps it's passing through the remnants of a neutron star collision? That is really interesting regardless.

True story: Way back in 1951/52 I spent 1st and 2nd grade in a one-room schoolhouse in rural Pennsylvania, near Shanksville where Flight 93 went down during 9/11. About 30 kids in 8 grades, one teacher, no running water and outhouses in the back. We kids used to fill a bucket of water from a hand pump and dump it into a big crock at the back of the class. It was a fantastic experience for an inquisitive and curious kid like me. I was able to listen to and learn from the lessons given to the other classes above me. I absorbed huge amounts far beyond my 6 and 7 year old self. But I never could figure out what was going on when long division was being taught. So...we were poor, so poor that the Periodic Table on our wall had only the Alkali Metals and the Lanthanide series. It's true. Trust me.

@fuzzblightyear145 7 місяців тому
well i suppose you could put that stability chart with the various isotopes on the 3rd axis ( with neutron count as the third axis) but i can't think of it's usefulness. Unfortunately you can't squeeze in any extra elements on the existing periodic table, except on the end, as each element is defined by the number of protons in the nucleus. And we have everything up to 118. And the periodic table looks like it does as elements with similar *chemical* properties are grouped together in the vertical columns. Which when you dive into it, is related to the structure of the electrons around the nucleus.

Since our models aren't going to predict before we create any new elements among the Island of Stability, there very well could be an isotope or two (or more) that are perfectly stable, even moreso than a U-238 etc. And who knows what secrets that could unlock...

Great video. Loved it. There are a few tiny errors in the brief section about Tc in medical imaging. Tc-99m with its 140 keV photon is the "work-horse" of nuclear radiology, and we use a gamma camera to collect those photons. There is a kernel of truth in that it plays an important role in medical imaging. However, it's not a "contrast agent" as radiologists typically use the term, and none of the images shown were of a nuclear medicine study using Tc-99m. The contrast agents used in the images you showed were gadolinium-based (MRI) and iodine-based (CT). These elements do have useful physical properties, but radioactivity isn't among them. Apologies if this has already been pointed out.
@youtube.scientist 7 місяців тому
I am not certain, but elements with more then 130 protons would be completely unstable because the strong positive electric field at nucleus would be capable of separating virtual electron positron pairs from the vacuum. Then the real positron would annihilate releasing energy that would destabilize any nucleus.

Regarding medical imaging: Tc is used in nuclear/scint/gamma cameras/SPECT. This video shows CT images (made from X-ray), which is a completely different technology.

Each larger element is simply the addition of a proton in the nucleus. Isotopes of that element are created by varying the neutrons in the nucleus, and ions are created by varying the number of electrons in the orbitals. Generally, as atoms get larger, they get more unstable (though this is not strictly always the case), so it becomes more and more difficult to find larger elements ocuring in nature. However larger elements can always be theoretically artificially created by combining smaller elements together. Therefore there are necessarily larger elements than what have been discovered.

The above is not really a problem if everybody is striving towards the goal of providing a well-rounded basic education to the students with the final result being grads with the knowledge and tools to continue learning in the field. Now to the problem. Were the "nuggets" that were not touched during your education not available at the time, or were they so new or controversial that somebody felt that such ridiculous nonsense had no place in your education? I am NOT trying to minimize your hard work in any way. I understand that earning a degree is not easy.
