Hydrogen and Helium
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.
These are elements in the periodic table. They also happen to make up the vast majority of earth's atmosphere.
Molecular oxygen is a bit over a fifth of the Earth's atmosphere, and molecular nitrogen is a bit under four-fifths of the Earth's atmosphere. There are also small amounts of oxygen and nitrogen in other atmospheric components such as carbon dioxide and ammonia.
The Moon has no atmosphere.

Nitrogen (78%) and oyxgen (21%). Argon comprises just under 1%.
Oxygen ( O2 ) : 21 % ; Nitrogen ( N2 ) : 78 % ;
The top three elements in Earth's atmosphere are nitrogen (78%), oxygen (21%), and argon (0.93%). These three elements together make up the vast majority of the gases present in the atmosphere, with nitrogen being the most abundant.
nitrogen and oxygen
No. The vast majority of them are burned up in the atmosphere.
The atmosphere on Mars is composed mainly of carbon dioxide (95.3%), with nitrogen (2.7%) and argon (1.6%) making up the majority of the remaining gases. There are also trace amounts of oxygen, water vapor, and other gases present.
