The ratios are about 78% nitrogen, 21% oxygen, 1% argon, and .04% carbon dioxide
The most abundant element in Earth's atmosphere is nitrogen, making up about 78% of the air we breathe. Oxygen is the second most abundant element in the air, at around 21%.
Nitrogen is the most abundant element in the earth's atmosphere.
Oxygen is the most abundant element in Earth's crust.
What_is_the_main_ingredient_in_air
Nitrogen.
oxygen
Hydrogen is the most abundant element found on Earth. Other abundant elements include helium, and oxygen, as well as silicon.
a. Nitrogen is the most abundant element in air, making up about 78% of the atmosphere.
The air (on ground level, not in a traffic jam!) is composed of ~80% N2, ~20% O2, 0-6% H2O (vary a lot), 0.03% CO2, 1% argon and then traces of other elements. The most abundant element is thus nitrogen N.
It is a solution of several gasses, the most abundant of which are nitrogen and oxygen.
Air is made up of: 78% Nitrogen 21% Oxygen1% Argon ppm levels of several other gases
There is incomplete info on the core, but Iron is likely to be it. However, since many elements in the crust are oxides and if you include water and atmospheric oxygen current information points that oxygen is the most abundant element on earth at about 45-50% of the Earth's mass (note its also the 3rd most abundant element in the universe) but element of the earth would be hydrogen (H) for every 1 oxygen on the earth there is 2 hydrogens (in normal air situations)Good answer=)(a wiki answers user was here..... not him^^^^^)Oxygen is the most abundant element in the earth's crust.
