Argon is the most abundant noble gas in Earth's atmosphere, at slightly less than one percent.
Depends on how many folks are eating Mexican food at any given time.
There are 8 electrons present in the valence level for all noble gases except helium. This is because in the outermost shell, known as the valence shell, noble gases (excluding helium) have a full octet of electrons, making them stable and unreactive.
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 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
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.
Metals are present on left side. Non-metals are present on right side. Noble elements are at extreme right in group-18.
Noble gases are chemically inert.
it's not
There are no metals in noble gases.All are gases in noble gases.
