Yes, but in very small quantities.
Very very small quantities, Mercury's atmosphere is basically a vacuum.
Hydrogen, Helium
Their gravity is too weak to hold on to atmospheric gases.
Any of them can, and all of them do.
The dominant gas on Mercury is oxygen, which makes up 42 percent of the planet's atmosphere, followed by sodium, which makes up 29 percent. Other gases include hydrogen and helium.
All of the atmospheric gases can be found trapped in magma and solidified rock.
Mercury
By volume, they are:Oxygen (42%), Sodium (29%),Hydrogen (22%),Helium (6%),rest (traces).
If the atmospheric pressure is 29.4 inches of mercury the corresponding inches of mercury is: 880.
Mercury has a thin atmosphere that is made up of many gases, including: hydrogen, helium, oxygen, calcium, potassium, sodium and water vapor. Mercury is the smallest planet.
The atmospheric gases carbon dioxide, methane and nitrous oxide are all greenhouse gases that help to heat the Earth.
it is hydrogen
The glass on the greenhouse stops temperature from leaving or entering like the gases do to the earth.The atmospheric gases are called 'greenhouse gases' based on the idea that the gases 'trap' heat like the walls of a greenhouse do
