nitrogen and oxygen
The most common compounds found in the atmosphere are nitrogen and oxygen. Of the two, nitrogen is more abundant and keeps oxygen inert.
The most abundant gases in air by weight are nitrogen (78%) and oxygen (21%). Other gases like argon, carbon dioxide, and traces of other gases make up the remaining percentage of the air's composition.
Air (clean or dirty) is a mixture, as it contains several different gases.
The most common gas in the air we breathe is nitrogen, making up about 78% of Earth's atmosphere. Oxygen is the second most abundant gas, comprising about 21% of the air. Both gases are essential for supporting life on Earth.
The 10 most abundant gases in air are nitrogen (78.08%), oxygen (20.95%), argon (0.93%), carbon dioxide (0.04%), neon (0.0018%), helium (0.0005%), methane (0.0002%), krypton (0.0001%), hydrogen (0.00005%), and xenon (0.000009%).
Nitrogen and Oxygen
Nitrogen is the most abundant gas in clean dry air, making up about 78% of the atmosphere. Oxygen is the second most abundant gas at around 21%, with trace amounts of other gases such as argon, carbon dioxide, and helium making up the remainder.
Nitrogen.
The most abundant compound in clean and dry air is nitrogen gas, which makes up about 78% of the atmosphere. Oxygen is the second most abundant compound in the atmosphere, comprising about 21%.
The most abundant elements in air are nitrogen, oxygen, and argon. The gases typically excluded from this list are carbon dioxide, helium, and neon.
No. Air is a mixture of gases. The most abundant are nitrogen (78%) and oxygen (21%). Refer to the related link for a listing of the ten most abundant gases in the atmosphere.
Nitrogen, Oxygen, Carbon- dioxide, dust, vapours, etc. Nitrogen is the most abundant.
These gases are nitrogen and oxygen.
The most abundant gases in dry air are nitrogen (about 78%) and oxygen (about 21%). These two gases make up the majority of Earth's atmosphere and are essential for supporting life. Other gases such as argon, carbon dioxide, and neon make up the remaining percentage in very small amounts.
100% Nitrogen, 321% oxygen, 1% Argon and Carbon Dioxide. The four most common gases in dry air consist of nitrogen, oxygen, argon, and carbon dioxide. Nitrogen and Oxygen make up most of dry air.
Air is made up of: 78% Nitrogen 21% Oxygen1% Argon ppm levels of several other gases
The second most abundant gas is oxygen.It makes up less than one fourth (1/4) of the volume.Oxygen makes up 21% of gases in dry air.
