What the atmospheric of mercury?
Mercury's atmosphere contains small amounts of hydrogen, helium, and oxygen. It also has even tinier amounts of sodium, potassium, calcium, and magnesium. Some of the gas particles come from the solar wind. Others are made by radioactive decay or when micrometeorites smash into the surface.

Mercury does not have what we would call an atmosphere. It is very, very thin , a collection of a few atoms per cubic meter, some being ionized from the surface. It is less th…an a trillionth of Earth's.
mercury has almost no atmosphere only a thin layer of helium and sodium gas.
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
It is much smaller than Earth, so has less gravity to hold an atmosphere. Also, its nearness to the Sun means that many molecules have been blasted away by the solar winds (st…reams of energetic particles from the Sun).
Yes, but in very small quantities. Very very small quantities, Mercury's atmosphere is basically a vacuum.
yes. but it is very thin like a jacket
Yes, but it is incredibly shallow and thin. It is a collection of molecules near the surface, most ionized by the Sun's radiation. (see related question)
The atmosphere of Mercury is made out of hydrogen,helium,oxygen,sodium,calcium,and potassium.
There is no atmosphere in Mercury due to the the combination of twofactors: 1) Due to the high average temperature on Mercury makes individualmolecules of the atmosphere move …very fast. 2) The low gravity (to be more precise: escape velocity) makes iteasy for molecules in the atmosphere to escape. In summary, if anyatmosphere develops on the planet (for example, something leakingout of the ground), it won't last long.
It has a very thin atmosphere
Because their small mass makes its gravity too weak to retain much gas around it. ;-)
Because it is too small and light. It does not have sufficient gravitational pull (which is proportional to mass) to keep its own atmosphere - the gases just escape.
