helium
No, Earth's atmosphere is mostly composed of nitrogen (about 78%) and oxygen (about 21%). Hydrogen makes up a very small fraction of Earth's atmosphere, less than 0.1%.
Hydrogen,mathane ammonia and water vapor.
The first atmosphere of the earth was probably mostly hydrogen with some simple hydrides such as water vapor, methane and ammonia. Vulcanism and asteroidal bombardment eventually replaced this with an atmosphere of mostly nitrogen, with carbon dioxide and some of the inert gasses.
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.
neptune's gases are ammonia and Methane.There are a couple others but these are only 2 of them!
helium
The atmosphere of the gas giants is usually made up of mostly of hydrogen and what?
Mostly hydrogen and helium.
Jupiter's atmosphere
Mostly hydrogen and helium.
No, Earth's atmosphere is mostly composed of nitrogen (about 78%) and oxygen (about 21%). Hydrogen makes up a very small fraction of Earth's atmosphere, less than 0.1%.
No. Jupiter's atmosphere is mostly hydrogen and helium with no free oxygen.
The four outer gas giants.
Yes. Mostly Hydrogen & Helium.
It is thin and mostly made of hydrogen and helium
peroxide and hydrogen.
yep
