This eventually paved the way for the emergence of complex life forms like plants and animals.
Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the air we breathe. Oxygen is essential for most life forms on Earth, playing a key role in respiration and supporting various biological processes. Both nitrogen and oxygen are nonmetallic elements in the periodic table with relatively low reactivity compared to many other elements.
