Answer:
Nitrogen ---- formed due to the transformation of ammonia (NH3)
carbon dioxide and water vapor ----- released into the atmosphere during volcanic eruptions
helium ------ mostly escaped Earth's atmosphere due to it is light mass.
Explanation:
Nitrogen are formed due to the transformation of ammonia (NH3) due to action of beneficial nitrogen, carbon dioxide and water vapor are released into the atmosphere during volcanic eruptions and helium mostly escaped Earth's atmosphere due to it is light mass. Helium has atomic mass i.e. 2 which is second lowest after hydrogen mass so due to its lighter weight it can't be stay in the atmosphere near to earth.
