No. Most of the atmosphere (regardless of the up to 1% water in the lower troposphere) is composed of nitrogen. Wikipedia lists the average composition of dry atmosphere, by volume, as follows:
Nitrogen, N2 78.084% Oxygen, O2 20.946% Argon, Ar 0.934%

Most of the oxygen is in the troposphere. Stratosphere contains ozone. It is the converted oxygen.
We know that oxygen is just a bit heavier than the air like carbon dioxide ,nitrogen etc.Besides that the main source of oxygen,the trees is in troposphere. Because of this reasons oxygen density is much heavier in troposphere than the stratosphere
We live in the troposphere, which is the lowest layer of the Earth's atmosphere. It is where most weather occurs and where we find the air we breathe.
Most of Earth's dry air is made up of nitrogen (about 78%) and oxygen (about 21%). Other gases such as argon, carbon dioxide, and water vapor make up the remaining composition.
The layer in the atmosphere that has the most air pressure is the troposphere, which is the lowest layer where most weather phenomena occur. As you go higher in the atmosphere, the air pressure decreases.
The layer of the atmosphere with the highest oxygen content is the troposphere, the lowest layer where most weather events occur. About 20.9% of the air in the troposphere is composed of oxygen.
Oxygen content is highest in the troposphere, which is the lowest layer of Earth's atmosphere where most weather occurs. Approximately 21% of the air in the troposphere is composed of oxygen.
Most of the oxygen is in the troposphere. Stratosphere contains ozone. It is the converted oxygen.
Yes, oxygen is found in the troposphere. It is one of the main components of the Earth's atmosphere, making up about 21% of the air we breathe.

The oxygen is mostly found in the troposphere. However most of the oxygen formed OZONE is found in stratosphere. It is due to the pressure of air there and the UV rays.
Oxygen
The troposphere is the layer of the atmosphere that contains the most air, as it is the lowest layer where most weather phenomena occur and a majority of Earth's atmospheric gases are concentrated.
Oxygen makes up about 21% of Earth's atmosphere. This percentage remains relatively constant at different altitudes within the troposphere, where most of Earth's weather occurs.
The troposphere
About 20% am. Most of it's nitrogen, though.
