Is hydrogen the second most abundant gas?
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.
Which is the most abundant isotope for hydrogen?
