The amounts of the elements in the atmosphere are:
~96.5% Carbon dioxide
~3.5% Nitrogen
0.015% Sulfur Dioxide
0.007% Argon
0.002% water vapor
0.001 7% Carbon monoxide
0.001 2% Helium
0.0007% Neon
trace Carbonyl sulfide
trace Hydrogen chloride
trace Hydrogen fluoride
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.
The atmosphere of Venus is composed mainly of carbon dioxide, along with a small amount of nitrogen and other trace elements. The amount of nitrogen in the atmosphere is relatively small compared to the amount of carbon dioxide, but as the atmosphere is so much thicker than that on Earth, its total nitrogen content is roughly four times higher than Earth's, even though on Earth nitrogen makes up about 78% of the atmosphere.
The atmosphere contains a range of interesting compounds in small quantities, including some based on hydrogen, such as hydrogen chloride (HCl) and hydrogen fluoride (HF). There are carbon monoxide, water vapour and molecular oxygen as well. Hydrogen is in relatively short supply in the Venusian atmosphere. A large amount of the planet's hydrogen is theorised to have been lost to space, with the remainder being mostly bound up in sulfuric acid (H2SO4) and hydrogen sulfide (H2S). The loss of significant amounts of hydrogen is proved by a very high D/H ratio measured in the Venusian atmosphere. The ratio is about 0.025, which is much higher than the terrestrial value of 1.6×10−4. In addition, in the upper atmosphere of Venus D/H ratio is 1.5 higher than in the bulk atmosphere. =)
venuses copisition is that it has light gravity so it doesn't hold air
witch is the reason why it has no air
carbon dioxide and water
it is a rocky planet
the mass of Venus is 0.82 times that of the Earth, and has a diameter of 12,100 kilometers
Venus has no oxegyn. Its air composition is 95% Carbon Dioxide
Venus and the earth have the same surface composition and have an atmosphere which has a complex weather system.
Venus. It's very similar in terms of size, mass and composition, although conditions on Venus are radically different.
size, mass and composition
bump
The Venus has a huge amounts of volcanoes!
Earth and Venus are similar in size, density, and overall composition.
the mass of Venus is 0.82 times that of the Earth, and has a diameter of 12,100 kilometers

Nickel and iron, just like the Earth.
Venus. It is similar in size, density, distance and composition.
Venus is made up of a central iron core and rocky mantle, similar to the composition of Earth..
