Hydrogen - Wikipedia
https://en.wikipedia.org/wiki/Hydrogen
WEBHydrogen gas is very rare in the Earth's atmosphere (around 0.53 ppm on a molar basis) because of its light weight, which enables it to escape from the atmosphere more rapidly than heavier gases. However, hydrogen is the third most abundant element on the Earth's surface, mostly in the form of chemical compounds such as hydrocarbons and water ...
