what are the noble gases relatively unreactive?

Noble Gases They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons.

Noble gases have highly stable fully filled electronic configuration which makes removal of electron extremely difficult. This accounts for the high ionisation enthalpy of noble gases.

The noble gases of Group 8A (He, Ne, Ar, Kr, Xe, and Rn) are all gases at room temperature (as the name of the group implies); since they are all unreactive, monatomic elements, their boiling points are extremely low.

All noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easily. Because of their high ionization energy and almost zero electron affinity, they were not expected to be reactive.

Question: The lightest noble gases, such as helium and neon, are completely inert - they do not form any chemical compounds whatsoever.

The Chemical Properties Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low chemical reactivity. ... Although noble gases do not normally react with other elements to form compounds, there are some exceptions. Xe may form compounds with fluoride and oxide.

Because noble gases' outer shells are full, they are extremely stable, tending not to form chemical bonds and having a small tendency to gain or lose electrons. ... Overall, noble gases have weak interatomic forces, and therefore very low boiling and melting points compared with elements of other groups.

Under ordinary conditions, noble gases are inert and don't form compounds, but when ionized or under pressure, they will sometimes working into the matrix of another molecule or combine with highly reactive ions.

This is a tendency, not a rule, as noble gases and other "inert" gases can react to form compounds. The group 18 elements include helium, neon, argon, krypton, xenon and radon. They are referred to as noble gases or inert gases.

Noble gases all have a complete octet (eight valence electrons), except for helium (which has only two electrons). Because this configuration is extremely stable as well as symmetrical, the noble gases are very unreactive.

Nitrogen, the unreactive gas On the other hand, nitrogen is not a noble gas. Two nitrogen atoms make up the nitrogen molecule (N2), so it has no free electrons like Argon and thus the same properties of a noble gas under nearly all uses. Indeed, nitrogen, which makes up 79.1% of our atmosphere, is very unreactive.

any of the gaseous elements helium, neon, argon, krypton, xenon, and radon, occupying Group 0 (18) of the periodic table. They were long believed to be totally unreactive but compounds of xenon, krypton, and radon are now known.

xenon and krypton(radioactive; can't say much) form most of the noble gas compounds so yeah in one way you can call them most reactive noble gases. Other noble gases take lots of effort (you can say) like temperature conditions and pressure to form compounds. How do noble gases exist in air?

The noble gases are the least reactive of all the elements but the heavier ones do form some molecules. Helium and neon never form molecules. They have completely filled electron shells with no have-filled orbitals available for making covalent bonds and they have very high ionization energies so they don't form ions.

Chemical Properties of Noble Gases Noble gases are the least reactive of all known elements. That's because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons.

The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don't react with anything. For this reason they are also known as inert gases.

The extremely stable noble gasses, including helium, neon, argon, krypton, xenon and radon, are all also nonmetal covalent elements. These elements form bonds with one another by sharing electrons to form compounds.
