Excepting accidents and nuclear weapons tests plutonium don't exist in air (or the concentration is too low to be measured).
The argon air abundance is 0,934 %.
Plutonium is normally solid and metallic.
500 Degrees kelvin.
Plutonium is a member of the actinoids family and in period 7 of the periodic table of Mendeleev.
Tin is not typically found in the air in abundance. The concentration of tin in the atmosphere is usually very low due to its relatively high density, so it tends to settle to the ground quickly after being released into the air.
Air and liquid water.
Plutonium can be released as waste from nuclear power plants and can be sold on the black market to make other nuclear devices.
The atmosphere layers contain huge abundance of air. These are divided into 4 layers.
The fractional abundance is calculated by dividing the abundance of the isotope of interest by the abundance of all the isotopes of the element. For chlorine-37, the percent abundance is 0.2434, or 24.34%.
Rainforests have been likened to the lungs of the planet. The abundance of vegetation and humidity help replenish and refresh the air.
