According to chemicool, the isotope argon-40, which results from the radioactive disintegration of potassium-40, makes up the great percentage of argon on Earth.
In the current periodic table, argon is estimated to have an average atomic mass of about 39.5 amu, which is extremely near to argon-40.
Radioisotopes are created using argon isotopes primary precursors. The radioactive K-38 that can be employed as a blood supply tracer was made from the argon isotopes Ar-40 as well as Ar-38. The radioactive Ar-41 that is created from Ar-40 is utilized to track gas flows.
Therefore, only two isotopes of argon, Ar-40 and Ar-38 exist in nature. if this were true, the atomic weight of argon 2 amu range.
