because earth has gas particles that can let helium go
Helium can escape because it is the least dense element after Hydrogen.
Hydrogen and helium
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.
Earth's lighter gases such as Hydrogen and Helium will rise to the top of the atmosphere. Since they are very light, they will easily be knocked awry by the solar wind, the stream of charged particles coming from the Sun.
Yes, like most gasses it can spread within currents and mix in with other gases. It is lighter than air, so on earth it will rise above the heavier gases of nitrogen and oxygen that make up our atmosphere. It does appear in the earths atmosphere in trace quantities, but the majority will escape earths gravitation pull and dissipate into space.
Gases
hydrogen and helium.
they come from earths atmosphere and gases
78% of the Earth's atmosphere is Nitrogen. Another 21% is oxygen, and the final 1% are other gases found is small amounts such as carbon dioxide, helium and methane.
These gases are hydrogen and helium.
Helium, and Hydrogen
The Abundant gases are Nitrogen, Helium, and other gases in the Secondary Atmosphere.
