There are six noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They are generally unreactive at room temperature.
Other elements that would have properties similar to radon include other noble gases such as helium, neon, argon, krypton, and xenon. These elements are all inert and have low reactivity due to their stable electron configurations. Like radon, they are all colorless, odorless, and tasteless gases at room temperature.
I think it would be easier to say what gases ARE noble gases. The six noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon. Any other elements are not Noble gases. This can include elements like Gold, Mercury, Calcium, Potassium, and barium.
I believe that the noble gases (helium, xenon, neon, argon, krypton and radon) do not form bonds with other elements, or amongst themselves (like oxygen bonding to form O2). This is because they are stable with full valence electron shells
Chemically, Helium is most like other noble gases - neon, argon, etc.
Most often to provide a chemically inert atmosphere in which a reaction can take place. Argon is preferred over the lighter noble gases for this purpose because argon is denser than air. And to make pizza!!! :)
Noble(nonreactive) gases like argon
There are no such elements: the atomic number is a unique property of each particular element and is not shared with any other element.

No. For one thing, a number of the elements (such as the noble gases: helium, neon, argon, etc.) don't like forming compounds at all, much less compounds with each other.

Basically all the noble gases as they have a stable electronic configuration and therefore they would not share their electrons with other atoms. -- Actually, the noble gases have been synthesized in labs to form noble gas compounds. Gold and platinum are both unreactive elements. There are probably more though.
Neon and argon, the two elements immediately below helium in column 18 of a wide form periodic table.

Because they already have a full outer shell of electrons, which is the most stable configuration.
