ایزوتوپ های آرگون. گاز نجیب آرگون دارای ۲۴ ایزوتوپ شناخته شده ( ۳۰Ar تا ۵۳Ar ) و یک ایزومر ( ۳۲mAr ) است که در این میان تنها سه ایزوتوپ ۳۶Ar, ۳۸Ar, و ۴۰Ar به طور طبیعی پایدار هستند. پایدارترین ایزوتوپ پرتوزای آرگون ۳۹Ar بوده که ۲۶۹ سال نیمه عمر دارد.
↑ هسته های پررنگ پایدار هستند ↑ Isotopic composition refers to that in air. 36Ar is actually far more abundant than 40Ar, universally. 40Ar is most abundant in air because most of it is radiogenic. Such 40Ar atoms are a decay product from 40K via electron capture, whereas 40K goes under mostly β - decay to 40Ca. 40Ar escapes the 40K - containing rocks into the atmosphere, thus making the argon in the air mostly 40Ar, not 36Ar. ↑ Believed to undergo β+β+ decay to 36S ( lightest theoretically unstable nuclide for which no evidence of radioactivity has been observed ) ↑ Used in argon - argon dating ↑ Cosmogenic nuclide ↑ Used in argon - argon dating and potassium - argon dating ↑ Generated from 40K in rocks. These ratios are terrestrial. Cosmic abundance is far less than 36Ar.
