Question

The point that the reason that most of the hydrogen has left the earth's atmosphere while the oxygen remains is because

the velocity of the hydrogen molecules is faster than the oxygen molecules on average.

the hydrogen molecules ionize at a lower temperature than oxygen molecules.

the hydrogen molecules ionize at a higher temperature than oxygen molecules.

the hydrogen molecules are less likely to form ionic bonds than the oxygen molecules

Thanks !!!

we know, rms speed of gas molecules, v_rms = sqrt(3*R*T/M)

here R ---> universal gas constant

T ---> temperature

M ---> molar mass

M_hydrogen < M_oxygen

so, vrms_hydrgen > v_oxygen

and v_rms_hydrogen > escape speed on the Earth's surface.
