See what Dr.Du said.mech-eng said:If we limit the reaction with other substances, does this not mean that they react with each other, and which would be wrong?
Thank you.
I think that even compounds with Xe-Xe covalent bonds have been synthesised.mech-eng said:If we limit the reaction with other substances, does this not mean that they react with each other, and which would be wrong?
Thank you.

I generally see it taught as "noble gases are inert under most conditions and only react in special circumstances," or some such qualification. But saying they're unreactive isn't a terrible approximation. Xenon's first ionization energy is comparable to that of O2, which means that oxidizing xenon is about as difficult as oxidizing oxygen. (In fact this was exactly how Neil Bartlett reasoned that xenon might be reactive--his experience with oxygenyl compounds of platinum hexafluoride. (sub-gripe: it's completely beyond me why he never won a Nobel Prize)).Vanadium 50 said:Why is this still being taught? It hasn't been true for 55 years. You can buy XeF2 out of a catalog - I just confirmed if I gave them my credit card number, I could have some on my desk by tomorrow. It's only about 3x as expensive as gold, by weight.
The noble gases are a group of chemical elements consisting of helium, neon, argon, krypton, xenon, and radon. They are located in the far right column of the periodic table and are known for their low reactivity.
Noble gases have a full outer electron shell, making them very stable and unreactive. This means they do not need to gain, lose, or share electrons with other elements to become more stable, unlike most other elements.
Although noble gases are generally unreactive, they can form compounds under certain conditions. For example, xenon can form compounds with fluorine and oxygen, but these are very unstable and only exist in laboratory settings.
Yes, noble gases have many practical applications. For example, helium is commonly used in balloons and as a coolant for nuclear reactors, while argon is used as an inert gas in light bulbs and welding. Neon is also used in neon lights and signs.
Yes, noble gases can be found in small amounts in the Earth's atmosphere. However, they are mostly obtained through the process of fractional distillation of liquid air. They can also be found in trace amounts in some minerals and natural gas deposits.
