∙ 12y agoThe unreactive gases are called the Noble Gases and appear in the rightmost column of the Periodic Table of the Elements. From lightest to heaviest they are:-
Helium (He)
Neon (Ne)
Argon (Ar)
Krypton (Kr)
Xenon (Xe)
Radon (Rn) which is radioactive.
There are also a large number of unreactive gases which are compounds.

∙ 11y agoGo down the list of noble gases and pick one. All of them are very unreactive.
There are six noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

What is the most unreactive gas?
Helium.
What is unreactive gas called?
The most common name for it is a "Noble gas" EDIT: Also Called An "Inert Gas"
An odorless colorless unreactive gas used in most uncandescent light bulbs?
argon
What is the unreactive gas in the second period?
Neon
How reactive is it xenon?
It is a noble gas and so very unreactive.
What is the most unreactive gas?
Helium.
Which is the most unreactive noble gas?
Helium
What is unreactive gas called?
The most common name for it is a "Noble gas" EDIT: Also Called An "Inert Gas"
An odorless colorless unreactive gas used in most uncandescent light bulbs?
argon
What is an unreactive gas element that in radioactive form is a byproduct of most nuclear explosions?
Helium (or alpha particles)
What is the unreactive gas in the second period?
Neon
Justify why the noble gas family is unreactive?
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).
Which unreactive gas is used to make fertilizers?
Nitrogen.
Does neon oxidize?
No. Neon is a noble gas and is unreactive.
What element has 3 energy levels and belongs to the most unreactive group?
The element is 'argon' and belongs to noble gas family.
The most unreactive family of gases?
The Noble Gas group, which is Group 18.
Does neon oxide exist?
No. Neon is a noble gas and is unreactive.
