The atmosphere of Venus consists mainly of carbon dioxide, and a small amount of nitrogen. The thick cloud cover is composed of sulfur dioxide and sulfuric acid droplets. Due to the dense atmosphere, the surface temperature ranges from 750 to 930 degrees Fahrenheit (398 to 498 Celsius). The surface pressure is 90 times that of Earth. That's like being one kilometer (more than half a mile) under the ocean.
Greenhouse gases make up a small percentage of the Earth's atmosphere, approximately 0.04% for carbon dioxide alone. When considering all greenhouse gases, including methane, nitrous oxide, and others, their combined concentration is about 1% of the atmosphere. However, despite their low concentration, these gases play a crucial role in trapping heat and contributing to the greenhouse effect.
Any atmosphere by definition is made of gas.
Noble gasses do not exist in large amounts in the earth's atmosphere. The noble gases in total sum up to less than 1% of the gasses in the earth's atmosphere.
By volume, hydrogen accounts for around 0.000055%.
Mars Atmosphere is made of 95% Carbon Dioxide (co2) and 3% nitrogen (n2)
Venus' atmosphere consists mostly of carbon dioxide, with clouds containing of sulfuric acid. There are also compounds of chlorine and fluoride.

About 21 of the Earth's atmosphere is made up of oxygen.
95.32%
Earth's atmosphere is about 21% oxygen by volume (for dry air).
Jupiter's atmosphere is made of 90% hydrogen and 10% helium
Approximately 78% of the Earth's atmosphere is made up of nitrogen gas.
The percentage of nitrogen in the Earth's atmosphere is about 78.
The percentage of oxygen in the atmosphere is approximately 21%. Nitrogen makes up 78% and the last 2% percent is a mixture of various different gases, mostly argon.
Argon makes up about 0.93% of Earth's atmosphere by volume, which is equivalent to around 0.04% by weight.
The percentage of oxygen in the Earth's atmosphere by mass is approximately 21.
The highest percentage in the Earth's atmosphere is nitrogen, at 78%. Then oxygen(21%) and CO2, 0.9%.
