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 is made up of 70 percent water and has an atmosphere made mostly of nitrogen?
Earth is the planet that fits this description. It contains approximately 70% water on its surface and its atmosphere is primarily composed of nitrogen, with oxygen being the second most abundant gas.
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.
Which planet is rockey and has an atmosphere made up of mainly nitrogen and oxygen?
That planet is Earth.
What is the only planet with an atmosphere that contains a large amount of nitrogen?
The atmosphere of Earth contains about 78.08% nitrogen. There has been no other place found that has this nitrogen in abundance, with Mars having only 3% as a remainder of its thin and low-pressure atmosphere.

What planet is Its atmosphere is mostly nitrogen?
Planet Earth - about 80%.
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.
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 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
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.
What are the atmospheric gases on the planet Earth?
The atmosphere is made up of 71% nitrogen and 28% oxygen. The other 1% is mostly made up of the noble gas argon.
Is Earth a big ball of gas?
No. It is a terrestrial planet like the other inner planets, meaning it is mostly rocky.
