Oxygen makes up 21% of the Earth’s atmosphere and 90% of the mass of water. It is arguably the most important element to life on Earth, and indeed it comprises roughly two thirds of the human body’s components. WebAny hydrogen that does enter the atmosphere quickly escapes the Earth’s gravity into outer space. Most hydrogen is produced by heating natural gas with steam to form syngas (a mixture of hydrogen and carbon monoxide). The syngas is separated to give hydrogen. Hydrogen can also be produced by the electrolysis of water.
