0.00005% of the atmosphere is hydrogen.
Hydrogen is found in the atmosphere.
* 22% of Mercury's atmosphere is hydrogen. * Venus does not have pure hydrogen in its atmosphere, but does have hydrogen chloride and hydrogen fluoride. * Earth has almost no hydrogen. * Mars does not contain any significant amount of hydrogen in its atmosphere. * Jupiter's atmosphere is roughly 90% hydrogen! * Saturn's atmosphere has even more: about 97% is hydrogen! * Uranus' atmosphere is 83% hydrogen. * Neptune's atmosphere contains 74% hydrogen.
The approximate mole fraction of nitrogen in the atmosphere is about 0.7808, and the approximate mole fraction of oxygen is about 0.2095. When combined, the mole fraction of nitrogen and oxygen in the atmosphere is approximately 0.9903.
The approximate percent of oxygen in Earth's lower atmosphere is around 20.95% by volume.
Hydrogen and HeliumThe major component of Uranus's atmosphere is Hydrogen.
Hydrogen is very scarce in the atmosphere: 0,oooo55 %.
composition of dry atmosphere by volume..... 78.09% nitrogen
The approximate percentage by volume of oxygen in Earth's atmosphere at location 2 is around 21%.
