This gas was carbon dioxide.
Oxygen is O and nitrogen is N.
Nitrogen (N2) is the most abundant gas in the Earth's atmosphere having percent volume of 78.8 compare to Oxygen 20.95 %, which falls on the second place after Nitrogen.
The most abundant gas in Earth's first atmosphere was likely hydrogen gas (H2), along with smaller amounts of helium and trace gases like methane and ammonia. Over time, these gases were modified as a result of volcanic activity and the emergence of life forms on Earth.
The least abundant gas in Earth's atmosphere is argon at 0.93%. The most abundant gas is oxygen at 78%.
The earths outer core's most abundant elemant is silicon. :)
Nitrogen
The troposphere is the most abundant layer in Earth's atmosphere. It is where most weather phenomena occur and contains about 75% of the atmosphere's mass.

Nitrogen is the most abundant gas but the interesting thing about it, is that we can not use it in the gaseous state.
The three most abundant gases in Earth's atmosphere are nitrogen (78%), oxygen (21%), and argon (0.93%).
Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the air we breathe. Oxygen is the second most abundant gas, comprising about 21% of the atmosphere.
