Helium
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.
In short, an element's valence shell is full and most stable when it contains eight electrons (this stability is the reason that the noble gases are so unreactive).
No. Neon is a noble gas and is unreactive.
No. Neon is a noble gas and is 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.
Noble gases are, for all intents and purposes, unreactive - there are a few noble gas compounds but you have to really work at it to convince noble gases to form bonds. Fluorine is an extremely reactive gas, hence it is not a noble gas. It is a halogen - the most reactive halogen of them all.
The element is 'argon' and belongs to noble gas family.
Helium, Neon, Xenon, Krypton, Radon, and Argon.
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.
All the noble gases are in the atmosphere: He, Ne, Ar, Kr, Xe, Rn.
