From left to right, the outer planets are Jupiter, Saturn, Uranus, and Neptune. The gas giants are made up primarily of hydrogen and helium, the same elements that make up most of the Sun. Astronomers believe that hydrogen and helium gases were found in large amounts throughout the solar system when it first formed.

What are the two main gases that make up the inner and outer planets?
Hydrogen and Helium.
Why are hydrogen and helium the two most abundant gases in the outer thermospere?
They are primordially gases.
What two gases make up 99 percent of Jupiter's atmosphere?
Hydrogen and helium make up 99 percent of Jupiter's atmosphere. These two gases are the most abundant elements in the planet's composition.

Is neptune a inner or outer planets?
neptune is a O-U-T-E-R outer planetThe third planet is the one that determines if a planet is inner or outer. Mercury and Venus are the only two inner planets. The others, including Neptune, are outer.
What are the two main gases of the planet Venus?
carbon dioxide and nitrogen
Where are the two main gases that make up stars?
The two main gases that make up stars are hydrogen and helium. These gases are primarily found in the stellar interiors, where nuclear fusion occurs, converting hydrogen into helium and releasing energy in the process. In addition to the core, hydrogen and helium are also present in the outer layers of stars, contributing to their overall composition and structure.
Name two gases that gives blue green color?
Uranus's blue-green color is also the result of atmospheric methane, ... The first two thirds of Neptune is composed of a mixture of molten rock, ...The outer third is a mixture of heated gases comprised of hydrogen, helium, water and methane. Methane gives Neptune its blue cloud color. Neptune is a dynamic planet
What are the two gases those do not take part in chemical reaction?
All Nobel gases very rarely react, they are very stable gases as they have a full outer orbital. (on the far right of the table)
Why is helium an exception to the noble gases?
A Noble Gas does not need to have eight electrons to be classed as such - it simply must have a full outer shell. The first shell can only hold two electrons, which is what helium has, so helium is a Noble Gas. The second and third shells hold eight electrons, which is why other noble gases can be seen as having eight electrons. However no Noble Gases have eight electrons in total - just eight in the outer shell, as the shells fill from the inside out...
