This one...the earth. The other planets are made up of critical gases,like methane, with frozen planets like Pluto made up of layers of frozen gases, such as a suspected layer of oxygen underneath layers of nitrogen and methane, and sulfuric gases which tend to snow out on the cold side of the planet.
Earth's atmosphere is mostly made up of nitrogen and oxygen; but the planet itself is more than just its atmosphere - overall Earth, like other terrestrial planets, is mostly made from rock (silicates) with a nickel-iron core. (By comparison, overall the outer gas planets are mostly made from hydrogen and helium.) By relative abundance, oxygen is also the most common element in the Earth's crust.
atmosphere is made up of gases in all planets. But if you mean planets that are mostly atmosphere, then those are gas giants (Jupiter, Saturn, Neptune, Uranus)
i think uranus
Yes. It's atmosphere is mostly Nitrogen.
Mercury has virtually no atmosphere. Planet with thinnest Venus has a extremely dense atmosphere of mostly sulphur compared to Earth. Planet with densest. Earth has a moderately dense atmosphere of nearly 3 quarters nitrogen and oxygen. Planet with 2nd from densest. Mars has a thin atmosphere of mostly carbon and some oxygen. Planet with 2nd thinnest.
Only one. The one we walk, talk and live on. 78% nitrogen, 21% Oxygen.

Neptune (NovaNet) There's something wrong here. Neptune is mainly a hydrogen atmosphere. Earth is the planet with a mainly nitrogen atmosphere, but the coldest is Neptune.
The atmosphere is mostly nitrogen. The atmosphere is above most of the water on Earth.
Yes. Titan's atmosphere is mostly nitrogen.
mostly C02 and some nitrogen
No. About 79% is nitrogen.
Mercury
The two planets that are mostly composed of methane and nitrogen are Uranus and Neptune. These gas giants have thick atmospheres made up primarily of methane and nitrogen, with smaller amounts of other gases such as hydrogen and helium.

Earth. 80% Nitrogen & 20% Oxygen.
