Why isn’t there much hydrogen found in the atmosphere?

Answer 1

The reason there is not much hydrogen in the atmosphere is because it is lighter than air, and so can easily escape the Earth's gravity.

Hydrogen,#H_2#, is one of the lightest gases that can be found on Earth. The other gas is helium, and these two gases are both lighter than air, because they have a high degree of buoyancy.

This indicates that it is being forced upward by the air below it rather than downward by the air above it.

Answer 2

Hydrogen is not abundant in the Earth's atmosphere because of its low atomic mass and high escape velocity. Due to these factors, hydrogen atoms in the upper atmosphere have a tendency to escape into space over geological time scales. Additionally, hydrogen can react with other elements to form compounds such as water vapor (H2O) or methane (CH4), which further reduces its concentration in the atmosphere. However, hydrogen is more abundant in other parts of the universe, particularly in stars and gas giant planets.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
