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.
mercury's atmosphere is MAINLY made up of sodium
Mars and Venus both have atmospheres made mostly of carbon dioxide. Earth's atmosphere is mostly nitrogen and oxygen. Mercury does not have an atmosphere.
The terrestrial planets in order from the thickest to thinnest atmospheres Venus, Earth, Mars, and Mercury. Since the gas giants are almost entirely made of gas, it is difficult to determine where the atmospheres end.
The four innermost planets in our solar system, Mercury, Venus, Earth, and Mars, are considered rocky, or terrestrialplanets, because they are made mostly of metals and carbon and silicon compounds (rock).
The inner planets (Mercury, Venus, Earth, and Mars) are made primarily of rock.
Mercury, Venus, Earth, Mars and Pluto are not gaseous. Pluto is sometimes not regarded as a planet. Jupiter, Saturn, Uranus and Neptune are gaseous, although the latter two may have a solid core of frozen gas.

yes, just like Venus, it is the hottest planet and its atmosphere is made up of purely carbon dioxide.
Mercury, Venus, Earth and Mars.
there all made of rock
The atmosphere is mainly composed of Carbon Dioxide and Nitrogen but Venus' atmosphere is equivalent to that of 93 Earth Atmospheres.
The first 4, Mercury, Venus, Earth, and mars are the ones.

The planets Mercury, Venus, Earth, and Mars are made of rock.
Mercury has an extremely thin atmosphere which is made up of atoms blasted off its surface by the solar wind, a constant stream of particles coming from the outer layer of the sun. Because Mercury is so hot, these atoms quickly escape into space. Unlike the stable atmospheres of Earth and Venus, Mercury's atmosphere is constantly being replenished.
