Neon-20 is used for the same things as any other natural isotopes of neon. E.G. it is used to make neon lights and helium-neon lasers. Neon-20 isotopic concentration may be important for some geological or volcanlogic studies.
Any neon, it is only a name here.
Neon can not rust, since neon is a gas, not a solid.
There is no compound of neon and silicon. Neon does not form compounds.
No, neon is not xenon.

Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
At room temperature, neon, which is an inert gas, is far and away less dense than water. Water, as you know, is a liquid at room temperature, and neon is never found in nature on earth as anything but a gas. A link can be found below.
Xenon is an inert gas; it is colorless, odorless and nontoxic. It is denser than helium, neon, and argon, but not as dense as radon.
Neon is a nonreactive gas. As it is a gas, it would only be found naturally (on earth) as a liquid if it were cooled down a LOT. There is no gas that is more dense than a liquid. Also, being nonreactive, neon doesn't bond with other elements without a LOT of energy, and even then, it is extremely unstable, so it would almost always be found as a gas. So, neon would be found in the air, or in gas pockets underground.
Neon, ammonia, methane, hydrogen, helium and water vapour are the best lifting gases and are all less denser than air.
The lightest element that is in period number 2 is lithium. Lithium is also the solid that is the least dense.
Neon in German is - Neon (!) Neon tube is Neonröhre
After Air is liqueifed and all the Oxygen, Nitreogen,Argon, and Carbon Dioxide are drawn of, you are left with all the rest of the noble gasses, Krypton, Neon, Xenon. Helium is not created by condensation of Air, but is separated from natural gas. Radon is radioactive, and is found anywhere where there is high amounts of Uranium. Although Neon is less dense than air, it isn't light enough to dissocate from our atmophere.

No. Neon is an element.
