What are the major gases of Mercury?

Answer 1

Approximately 79% nitrogen, 21% oxigen. Small amounts of other gases, and a variable amount of water vapor.
The atmosphere is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon and 0.039% carbon dioxide
Nitrogen, Carbon Dioxide, Oxygen

Answer 2

Mercury has no atmosphere worth mentioning. It's too small to retain an atmosphere, especially that close to the Sun. To the extent that there is ANY atmosphere, it is composed primarily of hydrogen thrown off by the Sun, tenuously held until the Sun blows it away again.

Answer 3

Mercury is not massive enough to sustain an atmosphere. It does have trace amounts of argon, nitrogen, carbon dioxide, water vapor, xenon, krypton and neon though. Gasses such as oxygen are abundant, but are in molecular form, i.e. locked up in a solid such as Iron Oxide.

Answer 4

The major gases on Mercury's exosphere include oxygen, hydrogen, helium, sodium, potassium, and trace amounts of calcium and magnesium. These gases are primarily sourced from the planet's surface materials, as well as interactions with the solar wind and micrometeoroid impacts.

Answer 5

Hydrogen, Helium, Oxygen. But they are very low in concentration.

Answer 6

Some gases that are present on Mercury are hydrogen, helium, oxygen and traces of ionized calcium, potassium, sodium, magnesium, and argon. There is a miniscule amount of water vapor present.

Answer 7

Europa has no atmosphere, but there is a magnetic field made of unusual gases from jupiter.

Answer 8

95% carbon dixode

Answer 9

anything with CFCs in them
