Mercury has too weak a gravity to hold on to an atmosphere. There is a very thin exosphere containing hydrogen, helium, oxygen, sodium, calcium, potassium. However, these are continually being lost into space, while being replaced by new matter. The latter come from the solar wind as well as radioactive decay of material on Mercury's surface.
