Mars has kept a thin atmosphere of carbon dioxide but has lost most of its hydrogen. The best reason is that
carbon dioxide molecules move faster and stay in the air longer
the gravity of Mars pulls weakly on light molecules
a hydrogen molecule has more kinetic energy than a carbon dioxide molecule at the same temperature
at the temperature of Mars, many more hydrogen molecules than carbon dioxide molecules move faster than the escape speed
