Question

Why are noble gases called inert gas?

Answer 1

I also want to add that noble gases have a few nifty purposes - there are a lot of metals that oxidise and corrode rapidly in air, and the alkali metals are also highly reactive to any moisture. A lot of the time, metals like, say, potassium can be stored in ampoules of argon gas. The gas preserves the metal and prevents corrosion and reaction, so it keeps its original sheen. And, as an added bonus, it stops it exploding at the first sign of moisture!

Answer 2

Quite simply because they are inert, in other words they will react with very, very little.

They have full electron shells and therefore do not easily form into ions, nor do they easily form covalent bonds. Hence they are usually found in their atomic form, and are gasses at quite low temperatures.

There are some compounds that do contain noble elements though, the first of which to be made was Xenon Hexafluoroplatinate in 1962, followed the same year by Xenon Tetrafluoride.

Answer 3

this is because they are chemically inert that is they  cannot react

they have obtain dublet or octet electron arrangement
