Carbon dioxide.
That's not quite right because carbon dioxide is about 95% of the atmosphere
of Mars.
The atmosphere on Mars is 95.72% Carbon Dioxide.
The predominant gas in the atmosphere of Mars is carbon dioxide. This accounts for 95. 9% of the volume of the atmosphere. Argon, oxygen and nitrogen are the other gases available.
The main gas on Mars is carbon dioxide.
(Wouldn't stay there if I were you!)
methane
There is a bit of confusion here. The Main gas of the atmosphere of Venus, carbon dioxide, is also the main gas of the atmosphere of Mars. This gas is a minor component of Earth's atmosphere.
There is no gas that fits this description. Carbon dioxide is about 95% of the Venusian atmosphere, but it's also about 95% of the atmosphere on Mars. Of course it's also a minor component of the atmosphere of the Earth too.
Krypton is a component of the Earth atmosphere.
Venus is the slowest planet with a rotational speed of 243 Earth days equaling one Venusian day.
Venus rotates (with respect to distant stars) on its axis once every 243 Earth days, and it completes an orbit around the Sun once every 224,7 Earth days. So, the Venusian day is longer than the Venusian year! For an observer on the surface of Venus it would take about 116,75 Earth days with the Sun rising in the West and setting in the East.
The principal gas in the Venusian atmosphere is carbon dioxide. This is also a minor component of the atmospheres of Earth and Mars.

Venusian atmospheric pressure is much greater than that of earth--IIRC about 90 bar of pressure vs only 1 for earth. (but on both density and pressure decline with increasing altitude.) 2. The venusian atmosphere is largely formed of CO, unlike that of earth. (but both have this gas) 3. The venusian atmosphere is much hotter than ours. (but both are warmed by the sun.) 4. The essential difference--the venusian atmosphere is not under biological control like ours is.
Oxygen
Yes
Significant components of the Earth's atmosphere include nitrogen, oxygen, and carbon dioxide.
yes , that all component that make up the atmosphere of earth
The gaseous part of the Earth is called the atmosphere. The solid portion of Earth is the geosphere, and the hydrosphere is the Earth's water component.
Water vapor
Krypton is a component of the Earth atmosphere.
Elemental nitrogen is found by taking a deep breath; it's almost 80% of our atmosphere. In compounds, nitrogen is found in fertilizers, amino acids, ammonia, and many other substances.
