Why is there no hydrogen in the atmosphere?

Answer 1

Hydrogen gas represents only a very small quantity of the gases in the earth's atmosphere. It's less than 1 ppm (parts per million) by volume. It really doesn't have a "function" in the earth's atmosphere as such.

Answer 2

Hydrogen is part - albeit a very small part - of the Earth's atmosphere. Typically hydrogen gas makes up about 0.000055% of the atmosphere. Most of the hydrogen in the Earth's atmosphere is combined with oxygen to make water vapor. A bit of it combines with carbon to make organic gases such as methane. Hydrogen is very reactive when mixed with other elements.

Answer 3

Hydrogen is very light and can escape the Earth's atmosphere easily due to its low mass and high velocity. Additionally, solar radiation can break down hydrogen molecules in the upper atmosphere, allowing the hydrogen atoms to escape into space.

Answer 4

The function of the earth's atmosphere is mostly to create weather and climate. This has a direct impact on most environmental activities.

Answer 5

The function of atmosphere is to protect earth from various harmful radiations. The ozone layer protecting from UV rays is an example.
