Short Answer:
Most or all planets had water.
Earth has liquid water.
Mars is the only other planet which almost certainly had significant liquid surface water for an extended period of time, perhaps for billions of years.
More information:
Perhaps all other planets, were likely formed with water but lost it.
Terrestrial Planets:
Mercury is just too close to the Sun to have ever had much water for very long, even at a time when the Sun was cooler than now.
Venus probably had water when it was formed and kept it for a few hundred million years, but then it was blown away by the solar wind. Water is a very light molecule and would disappear more easily than nitrogen, oxygen, carbon dioxide.
Earth has water, of course.
Mars had water for a long time.
Gas Giants:
Jupiter, Neptune, Saturn, Uranus are gas giants and may have some solid rocky material but are primarily made from gas and various types of ice. Some of that ice is water ice, though that being below the gas surface is not well characterized.
Dwarf Planets:
Dwarf planets, like Pluto, are often made up of icy materials or at least have icy surfaces over rocky materials, but the Dwarf Planets have never been investigated at close range.
Moons:
Some planetary moons have water, for instance the Moon (Earth) and Europa (Jupiter).

Which planet has is atmosphere mostly made of nitrogen?
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.
What planet has nitrogen and oxygen in it's atmosphere?
It is none other than our own planet Earth, which has nitrogen and oxygen in its atmosphere.
Almost all of the oxygen on the planet earth is found in the atmosphereis this statement true or false?
False. Almost all of the oxygen on Earth is found in the oceans.
Which planet is rockey and has an atmosphere made up of mainly nitrogen and oxygen?
That planet is Earth.
Which planet is made up of 70 percent water and has an atmosphere made mostly of nitrogen?
the planet we live in

What planet has nitrogen and oxygen in it's atmosphere?
It is none other than our own planet Earth, which has nitrogen and oxygen in its atmosphere.
What planet's atmosphere mostly nitrogen?
Mercury
Is mercury made of carbon and oxygen?
No. The element mercury contains only mercury atoms. The planet Mercury is made mostly of silicon, oxygen, and iron.
Which planet's atmosphere is mostly nitrogen and oxygen?
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.
Almost all of the oxygen on the planet earth is found in the atmosphereis this statement true or false?
False. Almost all of the oxygen on Earth is found in the oceans.
What planet is Its atmosphere is mostly nitrogen?
Planet Earth - about 80%.
Which planet is rockey and has an atmosphere made up of mainly nitrogen and oxygen?
That planet is Earth.
What is the atmosphere made of on planet earth?
It is made out of nitrogen and oxygen
Compare the four inner planets atmosphere?
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.
Which planet's atmosphere is 78 percent nitrogen?
The Earth has an atmosphere of 78% nitrogen (and 21% oxygen).
Does the planet mercury have any atoms?
The planet Mercury is a rocky planet that contains most of the same elements as Earth. It does not have an appreciable atmosphere, except for a trace of ionized vapor consisting mostly of oxygen, sodium, and hydrogen.
