The electron valence shell is filled and as a consequence the atom is very unreactive.
Noble gases have a very low chemical reactivity and have copletely filled the outer shell of elctrons.
Helium is an inert gas. It has 2 electons.it is non reactive.
inert gas inert gas inert gas
It is a colorless, odorless, tasteless, nontoxic, and nearly inert gas that heads the noble gas series in the periodic table
argon is an inert gas
All argon gas is inert.
That depends on what inert gas you're taling about.
no oxygen is not a inert gas
Carbon monoxide is not an inert gas.
Helium (He) is a noble (inert) gas placed in the group 18 of the Periodic Table.Helium falls in inert gas. It is stable and non-reactive.
The most inert gas in the atmoshere is nitrogen; the most noble gas is argon.
a inert gas is one that doesnt respond
