Planets defined: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Of these, all except Mercury have an atmosphere. Some atoms of various kinds have been detected near Mercury, suggesting a tenuous exosphere, composed of materials that have been sputtered off the surface by the solar wind. These atoms don't remain very long, and are accelerated away from the planet in a fairly brief period of time.
Terrestrial planet atmospheres are primarily composed of gases like nitrogen and oxygen, with small amounts of carbon dioxide and other trace gases, while Jovian planet atmospheres consist mostly of hydrogen and helium, along with traces of methane and ammonia. Terrestrial planets have thinner atmospheres compared to Jovian planets, which have massive, thick atmospheres made up of mostly hydrogen and helium.
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.
Yes
Venus and Earth are the two inner planets with thick atmospheres. Venus has a thick atmosphere composed mainly of carbon dioxide, while Earth has a diverse atmosphere containing nitrogen, oxygen, and other trace gases.
Outer planets like Jupiter and Saturn have thick atmospheres composed mostly of hydrogen and helium. Uranus and Neptune have atmospheres rich in frozen ices like water, ammonia, and methane. Strong winds, massive storms, and unique cloud formations characterize the atmospheres of these outer planets.
They are too hot or too cold. They do not have atmospheres.

yes, some other planets like Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune have atmospheres
Venus, Earth and Mars.
its made out of jaffa cakes
Seven of the eight planets in out solar system have atmospheres. Mercury is the only planet without one.
