Argon is the most abundant noble gas in Earth's atmosphere, at slightly less than one percent.
because they are gases, they are chemically inert and doesn't combine with other elements.
Argon.
It's the third most abundant gas in the atmosphere.
All the "noble" gases are in air: helium, neon, argon, krypton, xenon, radon.
Depends on how many folks are eating Mexican food at any given time.
There are eight in all noble gases (except helium) because that forms a "full level" so that they are noble gases and not reactive.
Noble gases have numerous important applications in lighting, welding and space technologyA certain amount of them is present in the atmosphere. Another important source is natural gas deposits, which usually have a certain amount of helium mixed in.Group 18 on the periodic table, or the last group on the right
For helium it is 1s2. For the other noble gases it will be ns2 np6 where n is the period in which the noble gas in present.
Noble gases have larger atomic radii than alkali metals in the same period.

noble gases
Noble gases have larger atomic radii than alkali metals in the same period.
The number of electron shells depends on the noble gas. The number of shells will be equal to the period in which the noble gas is present.
Noble gasses do not exist in large amounts in the earth's atmosphere. The noble gases in total sum up to less than 1% of the gasses in the earth's atmosphere.
Noble gases do not normally form compounds.
Noble gases do not react chemically with other noble gases.
Metals are present on left side. Non-metals are present on right side. Noble elements are at extreme right in group-18.
