Nitrogen
Hydrogen is 71% of the sun.
Yes, there is more carbon dioxide in the Earth's atmosphere than argon. Carbon dioxide makes up about 0.04% of the atmosphere, while argon makes up about 0.93%.
There is no such planet in our solar system. Perhaps you meant the atmosphere of the planet. The Earth has an atmosphere that's mainly nitrogen
The least prominent gas in the atmosphere is xenon. It represents no more than one percent on the air in the atmosphere.
Hydrogen and helium make up the majority of Jupiter's atmosphere, with hydrogen being the most abundant element. These two elements make up more than 99% of the planet's atmosphere.
helium
It is nitrogen and it makes more than 78% of the air.
Hydrogen is 71% of the sun.
This element is calcium. It is the fifth most abundant element in the Earth's crust and makes up more than 3 percent of the crust. It reacts with water and belongs to the 2nd group of the periodic table.
There is more than one element in planet Saturn, but 96% of Saturn is composed of hydrogen. There is also a little helium, and some ammonia ice, among others.
The atmosphere itself is NOT an element. The atmosphere is a mixture of all the gases around the planet. Some gases are elements, but because there is more than one gas in the atmosphere, it is a MIXTURE of elements not an element itself.
Hydrogen makes up more than 60 percent of a typical star's composition. Through nuclear fusion, hydrogen is converted into helium, releasing energy in the process.
Pluto absolutely has an atmosphere. Pluto's atmosphere is composed of 90 percent Nitrogen and 10 percent of the more complex substances such as methane.
Argon makes up roughly one percent of Earth's atmospheric gases. A more precise/exact amount would be 0.93%
You must be fishing for "water vapor". It varies a lot (the 'humidity'),but can be up to (not 'at least') about 4%.All other constituents of normal atmosphere are either much more ormuch less than than 4% .
The element argon (atomic number 18) constitutes about 1% of the Earth's atmosphere by volume. (More precisely, 0.93%)
Nitrogen is the gas that makes up about 78% of the Earth's atmosphere.
