nitrogen and oxygen
The top 10 elements in Earth's atmosphere, by volume, are nitrogen, oxygen, argon, carbon dioxide, neon, helium, methane, krypton, hydrogen, and xenon. Nitrogen and oxygen together make up around 99% of the atmosphere.

Elements can be produced in the sun through nuclear fusion reactions that occur due to the intense heat and pressure. These conditions are not present in Earth's atmosphere, which is why elements are not produced there. Earth's atmosphere primarily consists of gases and does not contain the necessary conditions for nuclear fusion to occur.

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 together make up about 99% of the atmosphere by volume. Most of the remaining 1% is argon. Under humid conditions water vapor may make up 2-4% of the air.

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.
