To find any Hydrogen at all you have to get up to 700km above sea level where small quantities are exchanged with the solar wind (and you have to keep ducking to avoid passing satellites). Hydrogen is far to reactive to exist freely in the air at sea level.

Here are 10 gases that make up clean air: In order of highest to lowest concentration they are Nitrogen, Oxygen, Argon, Carbon dioxide, Neon, Helium, Methane (CH4), Krypton, Hydrogen, and Xenon. There is small quantities of hydrogen in the air at sea level, 1 out of 2,000,000 atoms/molecules of air is hydrogen
