hydrogen
Nitrogen and oxygen are the two most abundant gases in the air. They are actually elements and not compounds. The two most abundant compounds would be water vapor and carbon dioxide.
There is no method to designate such properties. Only symbols with atomic number are mentioned.
oxygen
The Group 18 elements are called the noble gases or sometimes inert gases. Wikipedia has information on the noble gases, and a link is provided.
All the gases except the Noble(Inert) gases, which are monatomic.
No. Ions are just elements with charges.
Hydrogen
the answer is Nobel gases!!!!
Hydrogen and helium are the first elements produced in the universe after the big-bang.
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
Why were you not aborted??
You think probable to noble gases.
Helium is the most abundant of the Noble gases in the universe.
The noble gases which include neon.
The items that occur in nature as uncombined elements are the noble gases. These gases include xenon, helium, radon, argon, neon, and krypton.
The Abundant gases are Nitrogen, Helium, and other gases in the Secondary Atmosphere.
The noble gases are the elements in Group 18 of the periodic table. These are the inert gases, and they include helium, neon, argon, krypton, xenon and radon. The chemical symbols for these elements are He, Ne, Ar, Kr, Xe, and Ra, respectively.
