Nitrogen.
On both Venus and Mars, the most abundant gas in the atmosphere is carbon dioxide. On Earth nitrogen is the most abundant gas.
This gas is hydrogen.

Yes, water vapor is one of the most abundant gases in Earth's atmosphere. It varies in concentration depending on location and weather conditions, but it typically makes up around 1-4% of the atmosphere by volume.
The planet Uranus does have gas. One of the most abundant is methane which makes the planet look blue.
Quartz is one of the most abundant minerals on Earth's crust. It is composed of silicon and oxygen atoms and can be found in various forms such as amethyst, citrine, and agate.
One percent of the Earth's atmosphere is composed of argon, a noble gas. It is colorless, odorless, and inert, making it chemically nonreactive. While argon is not a significant player in terms of biological processes, it is the third most abundant gas in the atmosphere after nitrogen and oxygen.
No, but the element silicon is a major component of the mineral quartz, which is one of the most abundant minerals on earth.
It has a wide variety of its diet.
Helium is NOT one of the eight most common elements in Earth's continental crust. The eight most common elements are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. Helium is a noble gas and is not as abundant in the Earth's crust.
One way is two react sodium metal with chlorine gas 2Na(s) + Cl2 ---> 2NaCl However this would be a useless reaction as salt one of the most abundant compounds on Earth
