No Longer "Noble"; Argon Compound Found In Space
mbstone writes "Scientists at the University College of London — where argon was originally discovered in 1894 — have now found spectroscopic signatures of molecules of argon hydride (ArH), said to be produced via explosive nucleosynthesis in a core-collapse supernova in the Crab Nebula. The post-supernova molecular dust was observed by the Herschel Space Observatory shortly before it ran out of coolant in April.."
I don't get the connection between the title and the summary.
I masterbate to Obama and Limbaugh at the same time.. Wrap your head/dong around that one.
Do we categorize Argon as a non-noble gas, or do we redefine what a noble gas actually is?
Wait, I guess noble doesn't mean what I thought it meant, or there were already plenty of exceptions, as I just read this wiki article: https://en.wikipedia.org/wiki/Noble_gas_compounds

And now we are Argon?
Uruguay's president José Mujica: no palace, no motorcade, no frills
In the week that Uruguay legalises cannabis, the 78-year-old explains why he rejects the 'world's poorest president' label

"If anyone could claim to be leading by example in an age of austerity, it is José Mujica, Uruguay's president, who has forsworn a state palace in favour of a farmhouse, donates the vast bulk of his salary to social projects, flies economy class and drives an old Volkswagen Beetle.
But the former guerrilla fighter is clearly disgruntled by those who tag him "the world's poorest president" and â" much as he would like others to adopt a more sober lifestyle â" the 78-year-old has been in politics long enough to recognise the folly of claiming to be a model for anyone.
"If I asked people to live as I live, they would kill me," Mujica said during an interview in his small but cosy one-bedroom home set amid chrysanthemum fields outside Montevideo.
The president is a former member of the Tupamaros guerrilla group, which was notorious in the early 1970s for bank robberies, kidnappings and distributing stolen food and money among the poor. He was shot by police six times and spent 14 years in a military prison, much of it in dungeon-like conditions.
Since becoming leader of Uruguay in 2010, however, he has won plaudits worldwide for living within his means, decrying excessive consumption and pushing ahead with policies on same-sex marriage, abortion and cannabis legalisation that have reaffirmed Uruguay as the most socially liberal country in Latin America.
Praise has rolled in from all sides of the political spectrum. Mujica may be the only leftwing leader on the planet to win the favour of the Daily Mail, which lauded him as a trustworthy and charismatic figurehead in an article headlined: "Finally, A politician who DOESN'T fiddle his expenses."
But the man who is best known as Pepe says those who consider him poor fail to understand the meaning of wealth. "I'm not the poorest president. The poorest is the one who needs a lot to live," he said. "My lifestyle is a consequence of my wounds. I'm the son of my history. There have been years when I would have been happy just to have a mattress."
He shares the home with his wife, LucÃa Topolansky, a leading member of Congress who has also served as acting president.
As I near the home of Uruguay's first couple, the only security detail is two guards parked on the approach road, and Mujica's three-legged dog, Manuela.
Mujica cuts an impressively unpolished figure. Wearing lived-in clothes and well-used footwear, the bushy-browed farmer who strolls out from the porch resembles an elderly Bilbo Baggins emerging from his Hobbit hole to scold an intrusive neighbour.
In conversation, he exudes a mix of warmth and cantankerousness, idealism about humanity's potential and a weariness with the modern world â" at least outside the eminently sensible shire in which he lives.
He is proud of his homeland â" one of the safest and least corrupt in the region â" and describes Uruguay as "an island of refugees in a world of crazy people".
The country is proud of its social traditions. The government sets prices for essential
Argone.
xenon will combine with halogens. anything will combine with anything, you just need enough juice.
I want to delete my account but Slashdot doesn't allow it.
...declare me to not be noble. Denethor be damned.
Oh, wait, argon, not Aragorn.
Silence is a state of mime.
Neither --- you're not thinking sufficiently American.
Send the supernova a Cease & Desist letter. That'll teach'em to stop messing with us!
We can only explore space by going there in person directly. None of this 0.1 Earth radius up nonsense either.
Noble In Name Only
I thought we could rely on these gasses to stay true to their column on the periodic table, but, no, they've sold out, just like that whorish oxygen and hydrogen, which will twerk with even the most sordid elements of society.
We're just going to have to look elsewhere for the stability we crave at all levels.

they're not inclined to give, borrow, or take electrons from other elements
Except these aren't the words used on the wiki page. The word I was taught is "share". For example, Hydrogen has one electron and desires two for stability. So it shares one from Oxygen or Carbon, etc. And in that sharing, Oxygen (desiring two) gets its needs satisfied by sharing one each with two Hydrogens.

...you want to 1-up him you'll have to go for the quantum mechanic explanation of bonds. As far as *useful* models for chemical bonds go, even chemists use something pretty far from the "truth" . There are valence bond theory, orbital hybridization, resonance, and quite a few more.
When it comes to explaining nature, you use the model that is most USEFUL for what you want to explain, not for the most complicated one possible to impress your peers because you are so smart. :) That is why in many books atoms are still represented by red, white, blue "balls" and no one complains about it.
And by the way, the in the oxygen-hydrogen bond oxygen actually does sort of "borrow" the electron - the probability distribution for the location of that electron shifts towards the nucleus of the oxygen. That is why water molecules, while actually neutral (if not ionized), still act polar - the oxygen is essentially negative, the hydrogens positive. There is no equal "sharing".
The significant parts of this discovery are:
- a noble gas has been found in space (this confirmed people's expectations that argon-36 could be found as part of a supernova, even though argon-40 is much more common on Earth - note that argon-36 is also available on Earth, just in smaller quantities, it's not a new isotope)
- a noble gas molecule has been found in space (previously, argon compounds were only detected following Earth-based lab experiments)
The significant part of this discovery is not:
- that a noble gas can form a compound. Argon has had known compounds since 2003. Xenon has had known compounds since 1962, some of which are even stable at normal room temperature/pressure.
It means I can finally synthesize some Kryptonite! Superman, all your base will be mine soon! Bwahahahahaha
... It's not always easy to be noble under extreme conditions. Happens to the best of us!
That is not Nobel, its just Stuck Up.
Argon molecular ions were known well before that. The helium analogue, HeH+, was discovered in 1925!
Argon forms compounds without too much coercion. Back in the mid '60s chemists were playing with them regularly. As I understand it (I'm NOT a chemist and haven't done this myself):
Just mix argon and fuourine in a pressure vessel and heat it up. (VERY CAREFULLY! Fluorine gas is deadly!) You'll quickly get copious amounts of argon difluoride, tetrafluoride, and even some hexafluoride. These are stable enough to stick around once you bring things down to room temperatures.
Once you've got them, there are techniques for substituting other stuff for one or more of the fluorines.
But you DO have to be careful, even after the fluorine is out of the picture. I hear these compounds tend to be explosive, due to argon's propensity for dumping the riders and flying away alone.

Did a little checking. It's Xenon that they were playing with back then. Xenon is reasonably easy to convince to make covalent bonds, and some of its compounds are used industrially and available in commercial quantities.
Argon is less reactive, and they didn't get it to form compounds until 2000, with some encouragement from an ultraviolet light source to kick an electron up to another level.

> No Longer "Noble"; Argon Compound Found In Space
Typical Bitcoin fanboy phraseology, trying to spread FUD. In fact, gold is still a noble metal, even though it can be dissolved in "acqua regia". Similarly Argon Hydride (ArH) will not make argon less noble at all!
Well, if it is no longer of the Nobility, can it least get a peerage with a Knighthood?
