Question

Under which conditions will you expect the formation of compound with noble gases ???​

Answer 1

In normal conditions (Temperature: 20°C, Pressure: 1 Atmosphere), Noble Gases (He, Ne, Ar, Kr, Xe, Rn, Og) do not react because they have 8 electrons in their valence / outermost shell. That means, they follow octet rule. But, if we rarefy the noble gases (i.e., keep them in low temperature and high pressure), we force them to undergo chemical reactions.

First noble gas compound was formed by Neil Bartlett, which was Xenon Hexafluoroplatinate (XePtF6), formed as a product of Chemical Reaction between Xenon and Platinum Hexafluoride.

Chemical Equation:-

Xe (g) + PtF6 (s) → XePtF6 (s)

Answer 2

Noble gases are generally considered inert because they have a stable electron configuration with a full outermost electron shell. Therefore, they do not readily form chemical bonds with other elements.

However, under certain conditions, it is possible to form compounds with noble gases. These conditions include:

1. High pressure: Under high pressure, noble gases can be forced to react with other elements to form compounds.

2. High temperature: At high temperatures, the kinetic energy of the noble gas atoms increases, which can enable them to react with other elements to form compounds.

3. Electrical discharge: An electrical discharge can provide the energy needed to ionize the noble gas atoms, allowing them to react with other elements and form compounds.

4. Complexing agents: Complexing agents can bind to noble gas atoms and modify their electronic configuration, making them more reactive and allowing them to form compounds.

Overall, while it is possible to form compounds with noble gases under certain conditions, these compounds are generally unstable and have limited practical applications.
