Or Sumonium, as it's a big fella.
Japanese scientists are chuffed to bits to announce that they have discovered the so-far undiscovered superheavy element with atomic number 113, and have staked a claim to naming it - and so joining the big leagues of element-finding boffinry nations. According to a statement issued by the Japanese research institute RIKEN: …
What have they got against 115? It's rather what nature has got against them.
It's necessary first to find a combination of neutrons and protons that will be sufficiently stable that it lasts long enough to be detected and then to find two isotopes which are available in sufficient quantities and at affordable price that can be combined to make it.
"and then to find two isotopes which are available in sufficient quantities and at affordable price that can be combined to make it."
Given that this experiment involved firing zinc ions (element 30) at bismuth (element 83), am I safe in assuming that it was a simple case of 30 + 83 = 113 protons for the new element?
And that if we wanted to create element 115 by firing zinc ions in the same way, then the other element used would have to be element 85, i.e. Astatine? That is, an element that doesn't exist naturally, only via radioactive decay of other elements, is incredibly unstable in its own right- its longest-lived isotope has a half-life of 8.5 hours- and that has never been seen by the naked eye because (according to Wikipedia) "a mass large enough [for that] would be immediately vaporized by the heat generated by its own radioactivity".
Yes, I can see that this would make astatine *slightly* more difficult to work with in a similar setup than bismuth. :-)
Of course, I guess they could try other combinations of elements- they'd have to- but assuming I got that correct, I guess it illustrates your second point quite well. :-)
Well, as long as they do not do something incredibly or end-credibility-stupid with Astatine and drop two Ts and create massively deadly radiation along the way, then they won't create a dubious new element: ASININE????
sorry.... Could.. Not... Re... Cyst my elemental silliness, hahahaha
This element may well not have lasted for a fraction of a second..
From what we have seen so far, the heavier you go past a certain point, the less and less time it takes before the element decays.
Let's imagine that for some weird reason aliens had made a UFO out of element 120.
Ok, the time I just said to say OK and for you to think about it, the elements already gone. Even better, it irradiated the area as it did so. If we had a large mass of this and you were standing right next to it, well, I think it would be fatal. I think that's a fairly safe thing to say. It's going to be hotter than freshly extracted used nuclear fuel.
Bravo. It's good to see Japan at the forefront of research into nuclear chemistry.
I hope Reg readers will also join in a toast to Riken for the good work that they did following the tsunami and Fukushima accident. Riken staff measured radiation levels in various locations and provided a dependable summary.
Its purpose, like that of so much other research, is to be one of the foundations upon which greater projects may be built. Shoulders of giants and all that.
There are two reasons it is not called Japanite. Firstly, elements are generally suffixed with '-ium', as that is what IUPAC likes. Secondly, they wouldn't use "Japanium" for the same reason an element discovered in the UK is unlikely to be called "Angleterrium" or "Großbrittanium".
-ium is transliterated to umu in Japanese .. i.e. Calcium is karushiumu (カルシウム) and sodium is sojiumu (ソジウム）so it would be nihonnumu or I would guess nipponnumu. (double nn == ん otherwise you would get ぬ). There are "proper" kanji words for some of the elements.. but not being a science bod I don't know when you would use one or the other. Looking at my dictionary though some common compounds use the kanji word for one part and the transliterated English or German for other parts.
