The atmosphere is primarily composed of Nitrogen (N2), which accounts for 78%. Oxygen follows, accounting for 20% of its volume, with argon less than 1%. The remainder is composed of particulates and trace gases, including water vapor.

∙ 10y agoNitrogen makes up about 78% of Earth's atmosphere. Oxygen makes up about 21%.
Of the remaining gases, argon is a fraction of a percent, while carbon dioxide is only about 0.04%.
Water vapor suspended in the air can be from 1% to 5% of air by weight, and varies by location, temperature, and altitude.

What is upper explosive limit?
The highest concentration of gas in air is capable to producing flash of fire in presence of ignition source.
The air you breathe in is 78 of what gas as is 79 of the air you breathee out?
Nitrogen
What gas is not hazardous to breathe in low concentration?
Every day, you breathe nitrogen and oxygen along with many other gases. Helium is inert and poses no threat at all except if you breathe only helium and you deprive yourself of oxygen. In theory, any gas can be breathed in small concentrations since the concentration is what determines hazardous effects. Even Oxygen can kill you if it is in too high of a concentration.
What is the second most common gas found in the air we breathe?
Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
What does a Combustible gas indicator measure?
concentration of a flammable gas in air
