Are there chemical compounds for Kr, Ar, Ne, He? (stable in standard conditions)?

Question

There exist many chemical compounds of Xenon, but what about Kr, Ar, Ne, and even He?

Noble gases are not so inert, aren't they?

Answer 1

Referring to the article cited by another answerer, we see that the helium found in the fullerenes is present as a clathrate, rather than in actual chemical combination. When I last researched this subject about twenty years ago, several stable compounds of xenon had been found, and a very few marginally stable compounds of krypton, but nothing for neon, argon, or helium. Purported compounds of any of these are probably clathrates rather than compounds involving actual covalent bonding.

Answer 2

Yes, there are compounds for them. There are compounds for ALL of them. Even He. I saw at a pchem seminar that someone got He inside of benzene. And I have heard of many others.

Pretty much everything on the periodic table forms compounds. Except its hard to tell with some of the radioactive stuff.

In fact, you can even make these compounds metallic by applying pressure and lowering the temperature! This isnt science fiction, because in space these kinds of pressures and temperatures occur naturally leading to metallic nobel gases with different chemical properties!! You might be wondering how nobel gases could be metallic but remember that being metallic is a property characterized by having a very good flow of the bonding electrons.

Answer 3

As far as I can remember high school chemistry, the noble gases are stable, but that doesn't mean that its entirely impossible for them to chemically bond- it would just take a massive amount of energy for an electron to cause the atom to break up- What could also theoretically for bonding would be particles cooling down from a plasmatic state- but I've never heard of that happening...

Answer 4

Although they are noble gasses some of them form stable compounds in room temperature also and they are mainly oxides of the compounds.
Kr forms KrO4 and Ar forms ArS.

Answer 5

i'm sorry i'll need more details, but i was reading that a noble gas bonded with another gas at room temperature, with the catalyst being sunlight. it might have been a xenon compound.

Answer 6

If you make only one compound out of a nobel gas then you are able to publich it in a well respected journal. They are inert 99.9999% of the time

Answer 7

inert gases are stable at all temperates and pressure because they have fully filled orbitals and they cannot be ionized easily that requires lot of energy that is breaking of atom it is only possible at inner core sun by this we can conclude this as stable at all conditions

Answer 8

yes these gases are stable in standard condition and called noble gases

Answer 9

Krypton can form at least one stable compound.

Answer 10

i dont believe there are any naturally occuring compounds, but scientists have made compounds.
