Simply because compounds have been made from them. Xe and Kr in particular have had quite a few compounds made from them. This would mean they can be made from Radon too, but that is radiocative and only available in traces.
Inert (noble) gases have full outer valence shells, meaning they have almost a zero electron affinity. That means they are unreactive and in theory should not be able to form compounds.
However, the larger an element is, the weaker a hold it has on its outer electrons. In 1933, Linus Pauling theorised that highly reactive elements such as Fluorine and Oxygen, should be able to form compounds with the heavier noble gases.
In 1962, Neil Barlett noticed that Platinum Hexafluoride was able to ionize gaseous oxygen, and since the ionization energy for this was similar to that of Xenon, he saw if there was a reaction. They did react, creating Xenon hexafluoroplatinate, the first documented report of a noble gas compound.

What evidence do scientists have that the inert gases are not completeky inert?
Scientists have observed that certain conditions can cause inert gases like xenon, krypton, and argon to form compounds with other elements. Additionally, experiments have shown that inert gases can react with elements under extreme conditions, such as high pressure and temperature. These observations challenge the traditional view that inert gases are completely unreactive.
What is another word for chemically nonreactive?
inert as in the inert gases or "noble" gases
Can inert gases be stored with oxidizing gases?
No, inert gases should not be stored with oxidizing gases. Inert gases like nitrogen or argon are used to displace oxygen in storage containers to prevent combustion or oxidation reactions. Storing them with oxidizing gases could lead to potential fire or explosion hazards.
List of inert gases?
They are the noble gasses helium, neon, argon, krypton, xenon and radon and also less importantly the highly unstable and virtually non existent in nature: ununoctium. These noble gases have stable electronic configuration (they have completely filled valence orbitals / energy levels) and are chemically inert under STP. Hence they are considered to be inert gases.
Why are the elements helium argon and neon called inert gases?
As we all know that noble gases are also called INERT GASES, so the subgroup VIII of GROUP 'A' contains only noble gases and inert gases so helium and neon are also in VIII-A so they are inert gases.

Why are the inert gases called by this term?
The Noble gases were known as inert gases because it was believed that they were completely unreactive. This is no longer true as scientists have discovered compounds containing noble gas elements.
What evidence do scientist have that the inert gases are not completely inert?
From about 50 years the chemistry of noble gases is more and more better known; many compounds are known and the future is promising.
The noble gases are almost completely nonreactive for this reason they are sometimes called?
Inert Gases
Why were the noble gases at one time called the inert gases?
Noble gases are gases and have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and called inert gases.
What category is noble gases in?
Chemically inert Have completely filled valence orbitals
Is it true or false that Noble gases are inert gases?
Noble gases are inert gases because of a completely filled valence shell,hence they need not to satisfy their valency.
Why are noble gases nonflammable?
Noble gases have completely filled electronic configuration. and hence they are generally chemically inert.
Why are rare gases called rare gases?
Because they are chemically inert (or noble) due to the presence of completely filled orbitals.
Why are noble gases called rare gases?
Because they are chemically inert (or noble) due to the presence of completely filled orbitals.
Does noble gases react high or low?
Noble gases have completely filled valence orbitals and are hence stable or chemically inert.
Why are noble gases monotonic?
Noble gases have completely filled outer most shell. They are chemically inert and exist as monoatomic species.
