What 3 gases make up atmosphere?
The three most common gasses in our atmosphere are: nitrogen 78%, oxygen 21%, and argon <1%.
Can helium gas spread?
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.
