Which element has the highest abundance in Earth’s atmosphere?
Quick Answer
Nitrogen is the most abundant gas in Earth’s atmosphere, making up about 78% by volume.
The Full Story
Nitrogen is the dominant component of Earth’s atmosphere, at roughly 78 percent by volume. It is very stable as N2, which makes the atmosphere relatively unreactive compared with oxygen-rich mixtures. This stability helps protect many materials and organisms from constant rapid oxidation. Nitrogen is also central to agriculture because plants need it in fixed chemical forms.
