rock and other elements
By volume, they are oxygen and sodium.
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
it makes it very hot and oncreases the amount of radiation
Mercury has virtually no atmosphere due to its proximity to the Sun and its relatively low gravitational attraction force
Toledo Mercurys was created in 1947.
Toledo Mercurys ended in 1962.
mercurys period number is 80
Molecular oxygen, sodium, hydrogen, helium, potassium, argon, nitrogen, carbon dioxide, water vapor, xenon, krypton, & neon
mercurys surface material is made out of nothing but craters
Not all of the elements are present in the Earth's atmosphere.
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.
