Im pretty sure its oxygen and nytrogen
Nitrogen has made up the largest portion of Earth's atmosphere for most of Earth's history. It currently makes up about 78% of the atmosphere.
Nitrogen is the largest component of Earth's present atmosphere, making up about 78% of the total gases in the atmosphere.
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.
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.
Argon is a noble gas and does not react with other elements in the atmosphere, so it has remained relatively constant over time. The initial percentage of argon in the Earth's atmosphere was likely determined by the gases present during the planet's formation. The lack of significant processes that remove or add argon to the atmosphere has helped to maintain its percentage over time.

Many elements only form through high temperatures and pressures... both of which are present int the Sun - but not in the Earth's atmosphere.
Earths atmosphere is 78% nitrogen,21%oxygen,0.9% argon,and 0.03% carbon dioxide with very small percentages of other elements
the earths atmosphere is 77% nitrogen, 21% oxygen, with traces of argon, carbon dioxide and water.
Hydrogen I believe
earths crust , oceans and atmosphere
Oxygen is O and nitrogen is N.
