Explore: Argon Isotopes

Argon (18Ar) has 26 known isotopes, from 29Ar to 54Ar, of which three are stable (36Ar, 38Ar, and 40Ar). On Earth, 40Ar makes up 99.6% of natural argon

and argon measurements, while the newer method requires only one rock fragment or mineral grain and uses a single measurement of argon isotopes. 40Ar/39Ar

elements in the periodic table, 80 have isotopes considered to be stable. Overall, there are 251 known stable isotopes in total. Atomic nuclei consist of protons

universe, argon-36 is by far the most common argon isotope, as it is the most easily produced by stellar nucleosynthesis in supernovas. The name "argon" is

( 19K) has 25 known isotopes from 34 K to 57 K as well as 31 K, as well as an unconfirmed report of 59 K. Three of those isotopes occur naturally: the

isotopes of radon, polonium, and radium, which are all radiogenic daughters of uranium decay and are found in uranium ores. The stable argon isotope 40Ar

Complimenting He isotope data, neon isotope data additionally provide insight to thermal evolution of Earth's systems.        Argon has three stable isotopes: 36Ar

far the most common argon isotope, being the preferred argon isotope produced by stellar nucleosynthesis. The name "argon" is derived from the Greek
