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.
Planet Earth - about 80%.
Yes. It's atmosphere is mostly Nitrogen.
The four outer gas giants.
Mercury has a thin atmosphere mostly made of oxygen, sodium, hydrogen, helium, and potassium. Venus has a thick atmosphere of carbon dioxide with clouds of sulfuric acid. Earth's atmosphere is primarily nitrogen and oxygen with traces of other gases. Mars has a thin atmosphere mainly comprised of carbon dioxide.
Only one. The one we walk, talk and live on. 78% nitrogen, 21% Oxygen.

Planets with nitrogen atmospheres include Earth and Venus. Nitrogen makes up about 78% of Earth's atmosphere and about 3.5% of Venus's atmosphere.
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
Earth. 80% Nitrogen & 20% Oxygen.
