how much of the atmosphere is hydrogen?

Together they make up 99.96% of the atmosphere. All the remaining gases make up the remaining 0.04% of the atmosphere and Hydrogen is not even in the top 10. According to Wikipedia hydrogen makes up 0.000055% of the atmosphere but I wouldn't assume that it is all that accurate as it is such a small amount.

Atmosphere and Weather: One of the four gas giants, Saturn's atmosphere is much like that of Jupiter's. Hydrogen makes up nearly all of the atmosphere, with lesser amounts of helium and much lesser quantities of methane and ammonia.

ATMOSPHERIC WATER VAPOR. Water vapor varies by volume in the atmosphere from a trace to about 4%. Therefore, on average, only about 2 to 3% of the molecules in the air are water vapor molecules.

The atmosphere looks like a blanket of gas when you look at it from space or the ground. ... Overall, the atmosphere is made up of a few main molecules. The air above you is made of 78% nitrogen (N2), 21% oxygen (O2), 0.9% argon (Ar) and 0.04% carbon dioxide (CO2). That's it.

Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor.

Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.

Composition of the Sun's Atmosphere About 73% of the Sun's mass is hydrogen, and another 25% is helium. All the other chemical elements (including those we know and love in our own bodies, such as carbon, oxygen, and nitrogen) make up only 2% of our star.

The atmospheric gases include nitrogen, oxygen, carbon dioxide, water vapor, argon, and trace gases. Among the trace gases which are present in only small amounts, are neon, helium, krypton, and xenon. Nitrogen is the most abundant gas in the atmosphere. Nitrogen makes up 78 % of the Earth's atmosphere.

Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

Together, helium and hydrogen make up 99.9 percent of known matter in the universe, according to Encyclopedia.com. Even so, there is still about 10 times more hydrogen than helium in the universe, Nyman said. Oxygen, the third most common element, is about 1,000 times less abundant than hydrogen, she added.

Jupiter is composed primarily of gaseous and liquid matter, with denser matter beneath. It's upper atmosphere is composed of about 88–92% hydrogen and 8–12% helium by percent volume of gas molecules, and approx. 75% hydrogen and 24% helium by mass, with the remaining one percent consisting of other elements.
