Sorry but that is not the case. Air from sea level up to 10km is Nitrogen (78%), Oxygen (20%), Argon (1%), Carbon dioxide (0.04%), water (0.001% - 5%), Neon, Helium and Methane (all less than 0.002%). 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.
