∙ 6y agoMercury has no real atmosphere.
However it does have a very unstable tenuous one containing hydrogen, helium, oxygen, sodium, calcium and potassium. These exist in ionized forms in extremely low concentrations, making the atmosphere nearly indistinguishable from the vacuum of space.
One analysis found the following elements, most of which are probably derived from the solar wind, or (like sodium) released from surface materials.
42% molecular oxygen
29% Sodium
22% Hydrogen
6% Helium
5% Potassium
Traces of argon, nitrogen, CO2, water vapor, xenon, krypton and neon.
