I got my Chemistry degree in 1969 and even then they were coming up with these elements that existed only for nanoseconds. I decided then I really was not interested unless I could buy a pound of the stuff at Home Depot, so I am with you.
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?
To: Retain Mike
Some of my post that I used with contractions also had weird symbols on them once they were posted

Nope. Not true.
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.

And I just wallpapered the study with periodic table wall paper last week. Isn't that the way?

> I while back I saw a very interesting story about the guy that created the âperiodic 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.

Check the end of the article - this is stated there:
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.
Seriously?

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.

Seriously? Factually descriptive yes. Serious? No. There are no serious people at The Guardian.

It was a fragment from the exploded planet, Krypton.
[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.]

Political correctness continues to run amok.

Thank you, one of the long, unexplained questions that haunted my youth has been answered.
OK, 'nuther one, who wins in a fight, Batman or Green Lantern and why?
