NitrogenThis video tells you about nitrogen, which is a gas at room temperature and is the most abundant element in Earth's atmosphere.
Nitrogen is the seventh most abundant element in the universe and is a major constituent of the atmosphere on Titan, the largest of Saturn's 62 moons. (Anomalies in the composition of Titan's atmosphere have led some to suggest that Titan might even harbor life forms).
