I love that despite all the hardcore chemistry, physics and engineering behind synthesising Dubnium, it all comes down to 95 + 10 = 105

[@ragnkja]

But there's a lot of physics involved in choosing 95 + 10 rather than, say, 94 + 11 or 96 + 9.

[@tomt7028]

If you can be bothered explaining, what does decide between 95 + 10 or something else? I'd be interested to know.

I agree with the professor. Science, scientists and science enthusiasts are going to have to be the ambassadors between cultures and even within cultures as the world becomes more and more polarized along political and social lines. It's gotten so uncompromising and outright insane that we need more cool, logical, and especially humble minds. And there is no other profession with more humility than science.

Agreed. It's a noble profession, and the most noble stance in general, starting from a position where one admits: "I know that I don't know," then working hard to find knowledge, and even better, to share it.

[@cetyl2626]

Agreed...this sounds like the early 1930s in Europe.

[@thisnicklldo]

Well, sounds nice. A first step would be to take away prizes, especially the Nobel prize. Once all these humble scientists recognise that there's a likely discovery to be made, I'm afraid the humility is rather squashed by the race for glory. I understand that the discoveries represent a lifetimes work by the discoverer, frequently requiring a level of intuition and intelligence beyond the comprehension of mere mortals like me, and I too instinctively want to recognise their achievement. But the glory I want to bestow is a cause of great friction in the scientific process, and it would be better if I never got to bestow it, really - if we truly believe that big advances can only be made by cooperation. And perhaps the race for glory is a bit less glorious in those fields that simply require a huge investment of money, typically from the state, to determine the winner - I'm looking at you, transuranic element fabrication and you, particle physics. It's very interesting, but in the end neither Seaborg nor Organessian really 'discovered' Dubnium - they just made it according to a recipe devised by other physicists - brighter men as far as I'm concerened.

Dubnium was named after dubstep and was invented the first time someone dropped the bass. They also realized it starts being self-propagating at 105 decibels, particularly in auditoriums with a large excess of laser beams and smoke haze.

[@gsurfer04]

What I find fascinating about Dubnium is that its longest-lived known isotope is much more stable than its neighbours in the periodic table but it's an odd-number element.

[@tesseract2144]

@Michael Nope, the stability of an element as nothing to do with electrons, it is purely a nuclear phenomenon (plus, the relativistic effect of the electrons would be more or less the same between Dubnium 268/270 and its neighbors). And like the op said, it is very strange to see a nucleus that have an odd number of protons AND an odd number of neutron to be more stable than any other proton/neutron combination neighboring (in fact the odd/odd combination is typically so unstable that there are only four odd/odd combinations that are completely stable : 2H, 6Li, 10B and 14N although the 50V has and extremely long lifespan) But we can observe that these two isotopes have a number of proton and neutron close to semi-magic numbers (106 and 164 compared to 105 protons and 163/165 neutrons) which give the nucleus a little more stability. And given the fact that the typical nuclear shell model that is use to describe and predict the stability of nuclei doesn't apply very well due to the huge number of side effects a nucleus of this size have, it could indeed be that the global effect of 105 protons and a number close to 164 neutrons could be particularly stabilizing, i don't know if there are studies about this stability

[@wvdh]

@ tesseract: There are a few cases in which the stability and half-life of an isotope are influenced by the presence/absence of orbital electrons. Bound state beta decay and the inhibition of electron capture in some fully stripped nuclei are observed.

[@PhilReynoldsLondonGeek]

Dubnium was the last element known to the writers of the book I used when I did GCSE Chemistry (in the second cycle of GCSEs) - though they referred to it as hahnium then. Some of the periodic tables we had included rutherfordium, under the name kurchatovium. Elements up to meitnerium had been discovered by then, but of course no names were actually decided for them until some years later. I am not at all surprised rutherfordium was so named - it was Rutherford that first showed atoms to be mutable - and it is likely that dubnium's name was agreed as a "trade". Now, of course, we can get an element named after the source of one part of the experiment - livermorium being an example.

[@rayoflight62]

When I was studying chemistry, the last element on the periodic tables was element 103 Lawrencium, the last actinides, symbol Lw than changed to Lr. It also was subject of a dispute between USA scientists and USSR scientists - on who discovered it first. The IUPAC gave the credit to the US scientists. In the late '90 they changed mind, and split the credit for the discovery of Lawrencium among the two groups. Thanks for the video, very appreciated...

[@cj0815]

Usually, alpha decays are used to characterize heavy elements. Gammas are quite a bit harder to measure, you need precise energies to identify and it's harder to identify elements at low statistics. Alphas have the advantage that it's always two protons and two neutrons, they are emitted at monoenergetic bands, detection is moderately easy and with a series of decays you can very certainly identify the nucleus that the chain originated from. Fortunately the superheavies mostly decay by alpha emission and don't fission or beta decay.

[@TarisRedwing]

Thank You SOOOO much for updating some of the 2008 videos.

[@browndd]

I'm sure that you've probably been asked and answered this question on more than a few occasions. But out of curiosity is there a specific reason for the ubiquity of "ium" in the naming of elements?

[@webcucciolo]

Wow, four years and nobody answered. -um and -ium are the latin suffixes for neutral nominative, that is a name (subject of a sentence) of neutral gender (usually, a thing). In Italian, for the same reason, all these elements end in -o or -io, the masculine suffix (Italian language doesn't have neutral gender)

Well, when you "disturb" the electron you can talk about speed. Plus keep in mind that all of this is just models. The professors is just choosing the model that allows him to do the most straightforward explaination.

[@nigeljohnson9820]

What is the expected effect of relativistic valence electrons? Are there any implications on finding stable super heavy elements?

[@alexpotts6520]

It's not the electrons that cause radioactive decay - it's the nuclei. But you'd certainly expect relativistic effects in these heavy atoms, which would affect their chemistry in various, often hard-to-predict ways. (Though the simplest one is that heavy elements often form fewer bonds than elements higher up the group. For example, carbon and silicon form four bonds, tin usually forms four but can form two, lead forms two and you have to put in a bit of work to make it form four.)

[@nigeljohnson9820]

@@alexpotts6520 i am aware that stability is a function of the nucleus and chemical reactions are governed by the valence electrons. What interests me is the prospect of chemistry with a super heavy element. I had never before considered the effect of relativistic valence electrons. But you cannot do much chemistry with an element that has such a short existence and only exists as an ion. There are reports of a stability plateau around atomic number 160. The term stability is relative and may not indicate sufficient time to form a neutral atom, but it would be interesting if it did.

i did happen to read a while ago about "island of stability" expected to come after 120+ with vastly improved stability.

[@johnsheppard1476]

Just really curious about these super heavy elements and also the island of stability..And as I see the isotopes that were synthesized are wa-ay below that island-so it's like expecting,say,iridium-173 to be stable but it also has got a half life of fractions of a second but in this case we simply are unable to make a normal iridium-193 which is stable but it doesn't mean that stable iridium doesn't exist!So as I heard about element 117-tennessine that there were evidences found that it was still present in some rocks which formed less than a billion years ago which means that probably we simply just appeared too late to witness the super heavy elements in nature but they were there!At least I hope so..

[@archingelus]

So professor, i want to know what does this dubiousnium 105 is used for today?
