The elements, discovered by scientists in Japan, Russia and America, are the first to be added to the table since 2011, when elements 114 and 116 were added.
The four were verified on 30 December by the US-based International Union of Pure and Applied Chemistry, the global organisation that governs chemical nomenclature, terminology and measurement.
IUPAC announced that a Russian-American team of scientists at the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California had produced sufficient evidence to claim the discovery of elements 115, 117 and 118.
The body awarded credit for the discovery of element 113, which had also been claimed by the Russians and Americans, to a team of scientists from the Riken institute in Japan.

By the way I did not use contractions in this post because the final product appears with all these weird characters. It did not used to be like this. Maybe I am the only one bothered?
Some of my post that I used with contractions also had weird symbols on them once they were posted
Most of the transuranium elements occur "naturally," (a definition that only makes sense if we exclude humans from nature, which is a nonsensical idea) but their half-lives are so short that beyond plutonium they're very rarely (or never) observed outside of nuclear reactors or accelerators.
All that is necessary for an element to go into the chart is that it exist long enough to be reliably observed. For UUO, (118) the half life is believed to be <1 millisecond.
Isn't that the way?
A known issue at FR involving translation of UTF-8 to other character sets and vice-versa.
> I while back I saw a very interesting story about the guy that created the “periodic tableâ€, a Russian IIRC.
You mean Dmitri Ivanovich Mendeleev?
Mendeleev worked with Henry Moseley who figured out that Mendeleev had the periodic table out of order on several elements of similar atomic mass. Moseley fixed it and the credit was to be shared, but Moseley, 27, was shot in the head by a Turk at Galipoli and did not survive WW1.
Unfortunately the Nobel Prize is only awarded to living people, so Mendeleev took the credit and prize.
Now I have to rip it all out and replace it with the correct table.
Can’t be produced under the yellow sun of earth. Only exists under the red sun of Krypton (not to be confused with the Noble Gas, Krypton, which isn’t named “Krypton” on Krypton.)
This does exonerate Robert Lazar, at least as far as the elements he mentioned.
To a non-chemist it seems kind of silly to celebrate things that come into existence for only a microsecond. Islands of stability would be cool, though.
Factually descriptive yes. Serious? No. There are no serious people at The Guardian.
Well, before man-made global warming, our sun must have been red because I remember a Superman comic book from my youth where kryptonite was used to damage the super dude here on Erf.
Nope.
[Somehow, planetary fragments were able to reach Earth through interstellar space. How that happened is curious but by no means the most serious of the ontological and metaphysical problems still unresolved in the DC® Universe.]

Everyone’s forgetting Expensitanium, essential to defense projects like the F-35, etc...
“This article was amended on 4 January 2016. The reference to the new elements being “manmade” was changed to “synthetic” to follow Guardian style guidance on the use of gender-neutral terms.”
Political correctness continues to run amok.
It can only be found on Uranus.
OK, 'nuther one, who wins in a fight, Batman or Green Lantern and why?
