Mercury has a surface pressure that is near enough zero (or a vacuum), the planet holds no real atmosphere due to its small size. There are some trace gases at the surface, but not what one would call a proper atmosphere.
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
Hot and even more hot
By volume, they are oxygen and sodium.
mercurys surface material is made out of nothing but craters

my planet
It is made out of nitrogen and oxygen

it makes it very hot and oncreases the amount of radiation
The largest planet is Jupiter, with an atmosphere made mostly of hydrogen.
