nitrogen
The most abundant metal in the Earth's crust is iron. The most abundant element in the Earth's core is oxygen.
The metal that is most abundant in the lithosphere is iron. Over 5.6 percent of Earth's mass is comprised of iron.
On Earth, about 78% nitrogen and 21% oxygen.
The most abundant metal in the earth's crust is the post transition metal, aluminum. It is found at about 82,300 ppm. It is the third ranked element, with oxygen being first and silicon second.
Hydrogen is the most abundant element in the known Universe; helium is second.
Nitrogen is the most abundant element in the earth's atmosphere.
Nitrogen is the least abundant element in the atmosphere of the Earth. The most abundant element in the atmosphere of the Earth is oxygen.
oxygen
Oxygen is the most abundant element in Earth's crust.
Nitrogen is the most abundant element in Earth's atmosphere forming approximately 78 % of the total volume.
Nitrogen
Hydrogen is the most abundant element in the universe, but it is relatively rare in the Earth's atmosphere. It makes up only about 0.000055% of the atmosphere by volume.

The two Earth regions where oxygen is the second most abundant element by volume are the Earth's crust, after silicon, and the Earth's atmosphere, after nitrogen.
Oxygen is the most abundant element on Earth. It comprises 49.5 percent of the total mass (amount) of the Earth's crust, waters, and atmosphere.
Oxygen is the second most abundant element by volume in both the Earth's crust (after silicon) and in the Earth's atmosphere (after nitrogen).
Nitrogen is the most common element found in Earth's atmosphere, making up about 78% of the air we breathe. Oxygen is the next most abundant element in Earth's atmosphere, making up about 21%.
