SUMMARY

Noble gases are generally considered chemically inert; however, under extraordinary conditions, they can form compounds such as xenon difluoride (XeF2). This compound is commercially available and utilized as an etching agent in microelectronics, demonstrating that noble gas compounds are not merely lab curiosities. The discussion highlights that while noble gases are unreactive under most conditions, they can react under specific circumstances, challenging the traditional teaching that they do not react chemically with other substances.

PREREQUISITES
  • Understanding of noble gas chemistry
  • Familiarity with chemical bonding concepts
  • Knowledge of etching agents in microelectronics
  • Awareness of ionization energy and its implications
NEXT STEPS
  • Research the synthesis and stability of xenon difluoride (XeF2)
  • Explore the applications of noble gas compounds in industrial processes
  • Study the ionization energies of noble gases compared to other elements
  • Investigate the historical context of noble gas reactivity and Neil Bartlett's contributions
USEFUL FOR

Chemists, educators, and students interested in advanced chemistry concepts, particularly those focusing on noble gases and their applications in technology and industry.

I would like to ask about a question concerning noble gases. "Nobel gases don't react chemically with other substances."

Is this statement about nobles gases completely correct or partially correct?

Thank you

Ordinarily correct. In extraordinary conditions, compounds can be made, maybe not very stable.

Compounds like XeF2 are available commercially and are used as an etching agent in microelectronics. So I wouldn't regard noble gas compounds as a lab curiosity.

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.

So being commercially available, does that mean it is stable, or stable enough for some known storage period?

See what Dr.Du said.

I think that even compounds with Xe-Xe covalent bonds have been synthesised.

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.

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)).
