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.
Nitrogen
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.
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.
Yes, that's correct. Ozone concentration is typically highest at the point of release from the device, and it decreases as it disperses into the surrounding environment. This is because ozone is a reactive gas that can react with other substances in the air, reducing its concentration over distance.
The upper explosive limit (UEL) is the maximum concentration of a gas or vapor in air above which it cannot ignite or explode. This means that if the concentration of the gas exceeds the UEL, there is not enough oxygen present for combustion to occur. It is important to stay below the UEL when working with flammable substances to prevent explosions.

The gas you breathe in from the air is called oxygen.
Oxygen is approximately 21% of the air we breathe.
Argon, with a concentration of 0,934 % in the dried air.
Gas
It is a gas.
The stratosphere contains the highest concentration of the ozone gas. It is present as the ozone layer within it.
Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the air we breathe. Oxygen is the second most abundant gas, with a concentration of around 21%. Water vapor, carbon dioxide, and other trace gases make up the remaining composition.
This is the gas with the highest concentration in a given system.
