Uranus and Neptune both have thick, gassy atmospheres that were formed by the left-overs of the formation of the planets.
Neptune.
Jupiter and Saturn are mostly made of atmosphere, with Jupiter's atmosphere consisting mostly of hydrogen and helium, while Saturn's atmosphere is also primarily composed of hydrogen and helium, with traces of other elements.
Hydrogen is the most abundant light element found in the outer planets of our solar system, including Jupiter, Saturn, Uranus, and Neptune. It can exist in different forms, such as molecular hydrogen and metallic hydrogen, under the extreme pressure and temperature conditions found in these giant planets.
Gravity is the force that keeps an atmosphere in place, surrounding a planet. Since there is no actual roof or container holding in the atmosphere, gas can always leak away into outer space, if it is not held in place by gravity. So the stronger the gravitational force, the more atmosphere can be retained. Large planets have a lot of hydrogen in their atmosphere, but hydrogen leaks away from smaller planets. Large planets attracted more gas when they were originally formed, as well. Remember that the solar system itself, and everything in it, originally condensed out of an interstellar cloud of gas and dust.
Gas giants are planets whose atmosphere is predominantly composed of gases, such as hydrogen and helium. These planets have a small solid core surrounded by thick layers of gas. Examples of gas giants in our solar system include Jupiter and Saturn.

Hydrogen and Helium
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
Hydrogen and helium make up most of the atmosphere of the gas giants such as Jupiter and Saturn. These two elements are the most abundant in the outer planets due to their low molecular weight and the way they were attracted gravitationally during the early formation of the planets.
Jupiter and Saturn are mostly made of atmosphere, with Jupiter's atmosphere consisting mostly of hydrogen and helium, while Saturn's atmosphere is also primarily composed of hydrogen and helium, with traces of other elements.
The chemical reactions between Earth's atmosphere and the atmospheres of other planets would depend on the specific composition of each atmosphere. Interaction could lead to chemical changes, such as oxidation reactions or the formation of new compounds. However, without specific details on the atmospheres in question, it's difficult to predict the exact nature of the reactions.
Because Jupiter is mainly hydrogen.
The most abundant gas in the original planetary atmosphere was likely hydrogen, followed by helium. These gases are believed to have been present in large quantities during the early formation of planets in our solar system.
The relative size of the gaseous atmosphere - mostly due to the amount of hydrogen in that atmosphere.
Uncombined hydrogen can be found in the Earth's atmosphere, although it is rare. It is also found as molecular hydrogen gas (H2) in interstellar space and on the surfaces of gas-giant planets like Jupiter and Saturn.
