Noble gases have completely filled orbitals. They are stable and chemically inert (non-reactive). So generally they will not accept / gain electrons and dont form ionic compounds.
Because noble gases are very unreactive only a small number of compounds is known: halides, oxides, salts, especially from xenon. Some compounds are unstable.
Halogens can be gaseous, liquid or solid; noble gases are only gases.Halogens are very chemical reactive elements; only some compounds of noble gases are known.
Yes, noble gases can form compounds, but with great difficulty. And more so with the heavier gases (higher atomic number/weight) than with the lighter ones. The noble gases are generally considered to be inert, or lacking any reasonable way to form chemical bonds with other elements. That's what makes them noble or inert. Only in the laboratory can we "force" some inert gases to form compounds. And all these compounds are highly unstable.
Noble gases are generally unreactive due to their full outer electron shells, making them stable. However, under certain conditions such as high pressure or high temperature, noble gases can react with atoms of other elements to form compounds. This occurs as these conditions can force electrons from the noble gas to form bonds with other atoms, allowing them to combine.
An interesting fact about noble gases is that they do not have any reactivity. Some of the noble gases include helium, argon and neon among others.

It is a noble gas; noble gases are chemically inert. Some compounds have been synthesised however.
The elements that do not have quoted ionic radii are the noble gases. These elements do not form ionic compounds and therefore there is no crystallographic data. All of the other elements have ionic radii, these are either an "estimate" from the apparent size of the ion in different compounds, or a calculated value. Ionic radius is a useful idea but it should not be taken to literally, comparatively few compounds are truly ionic, most of them have some covalent character. The best examples of elements where the ionic radius is meaningful are the group 1, 2 metals, oxide ion and the lighter halogens.
There are thousands upon thousands of compounds and almost all elements - except some of the noble gases - are represented in compounds.
The class of noble gases (Helium, Neon etc. in group 18) There are two groups that come to mind when talking stability: the noble gases and the coinage metals. The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are very chemically stable and do not readily form compounds. Note that although Radon is chemically stable, it's not stable from a nuclear standpoint and will decay (but it is not reactive in the chemical sense). The coinage metals (such as gold, silver, and copper) are very unreactive. Note that the further an element is from Au on the periodic table, the more reactive it is (obviously the Noble gases do not follow this trend).
Krypton is a practically unreactive noble gas.

Xenon is an inert monoatomic gas. It isone of the "inert" gases It does form some compounds, such as unstable covalent compounds with fluorine. It does not form compounds containing Xe ions.
The group on the far right of the periodic table of elements will not bond to form compounds. These are the Noble Gases aka Inert Gases and are the elements of Group 18, which includes helium, neon, argon, krypton, xenon, radon, and element 118. I think that's all of them. I am not 100% confident that this list is entirely inclusive so there may be some other element(s) that do not form compounds. I am sure however that Noble Gases do not react due to the fact that their electron shells are full.
