yes
The atmosphere does not have helium and hydrogen because the two gases are too light to be there. Instead they are in the exosphere, above the atmosphere.
hydrogen
Hydrogen
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.
Earth's atmosphere?Yes.0.0000055 %

By volume, hydrogen accounts for around 0.000055%.
Hydrogen is rare in the atmosphere because it is light enough to escape Earth's gravitational attraction.

Yes. Hydrogen is part - albeit a very small part - of the Earth's atmosphere. Typically it makes up about 0.000055% of the atmosphere
The most abundant element in earth's first atmosphere is nitrogen. This is a gas which makes 78% of the earth's atmosphere.
Jupiter's atmosphere is bigger than the Earth's and is mainly hydrogen plus quite a bit of helium.
Hydrogen
Hydrogen is explosive!!!! What about the earth's atmosphere? That is about 80% nitrogen.
In the Earth atmosphere hydrogen exist only as traces: 0,000055 %.
