The argon air abundance is 0,934 %.
Argon is a non metal element. Atomic mass of it is 39.94.
Ar 40 is the most common isotope, accounting for 99.6% of the total (by weight).
The natural abundance of Br-81 is approximately 49.31%.
The abundance of selenium in the atmosphere of Earth is very low, with concentrations typically ranging from 0.1 to 1 nanograms per cubic meter of air. Selenium is not a major component of Earth's atmosphere and is mainly found in soil, water, and food sources.

Ar
It is 87.3 K.
There are three natural isotopes.
Argon is a non metal element. Atomic mass of it is 39.94.
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.
Helium, Xenon, Neon, Krypton, and Radon.
Air and liquid water.
For most people there is absolutely no reason to buy any argon in their lifetimes.
Excepting accidents and nuclear weapons tests plutonium don't exist in air (or the concentration is too low to be measured).
Argon is very unreactive as it is a noble gas. Its common oxidation number is zero.
The atmosphere layers contain huge abundance of air. These are divided into 4 layers.
