Earth's first atmosphere contained hydrogen and helium but this was soon stripped away. Another atmosphere began to form and contained hydrogen, water vapour, methane, ammonia, nitrogen and carbon dioxide among other gases.
Oxygen. Earth's early(first) atmosphere is believed to contain hydrogen cyanide, carbon dioxide, carbon monoxide, nitrogen, hydrogen sulfide, and water. but still it only had little to no oxygen.
Nitrogen is the most common element in the Earth's atmosphere.
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%.
Saturn has an atmosphere, but it is not like Earth's. Saturn's atmosphere is composed primarily of hydrogen with some helium, small amounts of methane, ammonia, and trace other gasses. Earth's atmosphere is primarily nitrogen and oxygen with small amounts of water vapor, argon, carbon dioxide and trace gasses.

The composition of Saturn's atmosphere is primarily hydrogen and helium. There are trace amounts of oxygen, methane, ammonia and nitrogen.

In the Earth's Atmosphere; Nitrogen, this makes up about 78% of the Air we breathe.
The three primary gases that make up the atmosphere of Uranus are hydrogen, helium, and methane. Hydrogen is the dominant gas, followed by helium, while methane makes up a smaller but significant portion of the atmosphere.
Nitrogen
Approximately 79% of the earth's atmosphere is nitrogen, by volume, and approximately 21% of it is oxygen. There are small amounts of other gasses in the atmosphere, such as carbon dioxide, carbon monoxide, hydrogen, helium, argon, radon, propane, methane, ...etc. But primarily nitrogen and oxygen comprise our atmosphere.
carbon, hydrogen, oxygen, and nitrogen.
Ammonia has the chemical formula NH3; therefore, the elements contained in it are nitrogen and hydrogen.
It is nitrogen, followed by oxygen.
no it's nitrogen and oxygen
