The most important elements in the Earth's atmosphere are N (nitrogen) and O (oxygen).
Hydrogen and Helium
The top 2 are nitrogen and oxygen.
List the compounds so I can answer your question. I would imagine Carbon Dioxide and Carbon Monoxide would be the first 2.
The sun is 75% hydrogyn, 23% hylium, and 2% everything else. That is all I know.
core and atmosphere
Nitrogen (78 %) and oxygen (21 %).
2
Nitrogen 78%, Oxygen 21%, all others 1%.
Oxygen is O and nitrogen is N.
The transition elements are placed in center of periodic table. Examples are: zinc and copper
Nitrogen makes up 72% of our atmosphere I believe. It's definitely the most abundant element. The second is Oxygen.
Hydrogen and Helium
carbon dioxide and nitrogen are 2.
The top 2 are nitrogen and oxygen.
"in our atmosphere" you 2 year old illiterate. and its Nitrogen
that would be oxygen and nitrogen
