These are the concentrations of gasses in the atomosphere:
Nitrogen------78.08%
Oxygen------20.95%
Water------0 to 4%
Argon--------0.93%
Carbon Dioxide------0.036%
Neon-----0.0018%
Helium----0.0005%
Methane--0.00017%
Hydrogen--0.00005%
Nitrous Oxide--0.00003%
Ozone--0.00004%
However the higher you go in the atmosphere the higher the concentration of oxygen.
the lower part of the Earth's stratosphere is mostly composed of ozone molecules. Ozone plays a crucial role in absorbing and filtering out harmful ultraviolet radiation from the sun.
In the upper part of the Earth's atmosphere, you will mostly find gases such as nitrogen and oxygen. This region is where most of the Earth's weather occurs, including clouds, precipitation, and the ozone layer. The upper atmosphere also contains traces of other gases such as carbon dioxide, argon, and helium.
The inner core is the densest part of the Earth, with a composition of mostly iron and nickel. It is solid due to immense pressure, despite the high temperatures.
Oxygen
The part of the Earth that is mostly composed of iron and nickel is the core. The core is divided into two parts: the inner core, which is solid, and the outer core, which is liquid. The presence of iron and nickel in the core gives Earth its magnetic field.
The atmosphere of the Earth is a gas, not a liquid, and although it does contain oxygen, that is just one part of the atmosphere, which is mostly nitrogen.
The Earth's crust is made mostly of silicate minerals. Silicate minerals are the most abundant minerals in the Earth's crust and are composed of silicon and oxygen atoms.

centre part of earth mostly made iron
The volume of Earth's lithosphere is estimated to be around 1010-1011 cubic kilometers. It is the outermost layer of the Earth made up of the crust and the upper part of the mantle.
Oxygen is necessary for most organisms to carry out their life functions.
The inner core is the densest part of the Earth, with a composition of mostly iron and nickel. It is solid due to immense pressure, despite the high temperatures.
