Hydrogen is very scarce in the atmosphere: 0,oooo55 %.
hydrogen
the most abundant gas of the atmosphere is nitrogen with high percentage 78.09
Universally hydrogen is by far the most abundant gas, accounting for about 88% of the atoms in the universe. The second most abundant gas is helium, as both of these elements are formed in stars. On earth hydrogen gas is actually fairly rare. This is simply that due to its extremely low mass it can easily escape the atmosphere, and as there aren't very many natural sources of hydrogen gas what is lost is not replaced. Note that this only applies to hydrogen gas: the element hydrogen is the tenth most abundant on earth.
the most second abundant gas is oxygen
The most abundant element in earth's first atmosphere is nitrogen. This is a gas which makes 78% of the earth's atmosphere.
This gas is hydrogen.
hydrogen and nitrogen (I think)
In the Earth's Atmosphere; Nitrogen, this makes up about 78% of the Air we breathe.
These gases are hydrogen and helium.
