New Element 118
-
Scientists said they smashed together calcium with the manmade element Californium to make an atom with 118 protons in its nucleus. The new element lasted for just one millisecond, but it was the heaviest element ever made and the first manmade inert gas
I think we need better standards than that. Should we name an element that is stable for only 1 millisecond? And only one atom?
most of the superheavy's have only been produced a handful of times and possibily excluding a theorectical "plateau of stability" are all so massive that they're extremely unstable becuase the strong force can't effectively reach across the entire nucleus.

They've known about Administratium for decades, but actually proving it did something ... took time. :rolleyes:

There are plenty of named particles which decay faster then that. They only show up as resonances in collision spectra. In that energy relm one milisecond is an extrememly long time, it is 1012 femtoseconds after all.

Hey, why all the fuss. After all it's like Jumping Jack Flash, it's a gas, gas, gas. ;P

That's the first time anyone has said that to me as being the reason why large atoms are unstable. But it makes so much sense... Cheers, Jon

Claims look legit this time. Revisiting one of physics' most embarrassing cases of scientific misconduct, researchers from Russia and the United States announced Monday that they have created a new super-heavy element, atomic number 118. Article link[^].

It BSOD's so fast. Maybe they should call it VISTium , once they are sure it exists for real. Marius

Yep, unlike gravity and electromagnatism which have 1/r/r falloffs, the strong force is constant for a distance d and then falls off to zero. If part of the nucleus vibrates outside the range of the strong force the net potential on it goes from negative (atractive) to positive because only yhe EM force is acting on it. At taht point the atom pushes itself appart. This is only a first approximation description, the reason heavy elements have more nuetrons than protons is because each nuetron boosts the strong force only while protons boost both the strong and EM.

um... ok... :~ who's funding this stuff anyway? oh well, I guess I just don't get it.. :suss:

Mostly governments, the giant particle accelerators have gotten too expensive for anyone else. There's a reason they're largely international colaborative projects as opposed to mononational prestige ones.

I guess I just don't see the purpose. I mean, surely they must have known this 'element' would only last as long as it did, what, a few milliseconds... Is there any practical or even theoretical knowledge that comes of projects like this? I'm (obviouslly) not in that field so I wouldn't know. Add on top of that a media's version of the project and you've got the blind leading the blind so to speak.

It proves the theory.
The evolution of the human genome is too important to be left to chance.

yes, but after injecting a couple of Service Packs, it becomes stable :-D Steve
