Helium is considered the most unreactive gas because it is a noble gas with a full outer electron shell, making it very stable and unlikely to react with other elements.
It is a noble gas and so very unreactive.
Xenon is classified as a noble gas on the periodic table due to its full outer electron shell, making it stable and unreactive under normal conditions. It is located in Group 18 (VIII A), Period 5 of the periodic table.
Argon is more dense than air.
An unreactive gas is called inert gas. These gases are also known as noble gases because they are very stable and do not easily undergo chemical reactions with other elements. Examples of inert gases include helium, neon, argon, krypton, xenon, and radon.
The unreactive elemnyt in period 3 is Argon, Ar, a noble gas

Helium
Nitrogen.
No. Neon is a noble gas and is unreactive.
No. Neon is a noble gas and is unreactive.
Krypton is an unreactive gas.
It is a noble gas and so very unreactive.

It is because zeon is a noble gas &unreactive
He- helium it is a noble gas (very unreactive)
Neon (Ne) is a noble gas, very unreactive.
