Let x be the relative abundance of C l 3 5 then (1-x) is the relative abundance of C l 3 7 . In other words, in every 100 chlorine atoms, 75 atoms have a mass number of 35, and 25 atoms have a mass number of 37. The ratio of 36 Cl to stable Cl in the environment is about 700 x 10-15: 1 (Bentley et. So for example, there are two stable isotopes of chlorine, there's one version of chlorine known as chlorine 35. All other isotopes have half-lives under 1 hour, many less than one second. The low-δ 37 Cl, Cl-poor basalts approach the composition of uncontaminated, mantle-derived magmas. This is because chlorine contains two different isotopes, chlorine-35 and chlorine-37. The range of Cl atomic weights in nature and in laboratory . (In order for them to be atoms of the same element, their number of protons would be the same.) This results from the relative abundance of 75.76% of chlorine-35 and 24.24% of chlorine-37. The method for laser separation of chlorine isotopes includes irradiating a starting gas in the form of hydrogen chloride HCl with resonance infrared radiation with wavelength 3.782 mcm, subsequent exposure to laser radiation in . Chlorine is a major component in fluids that are derived from the subducting slab (Kent et al., 2002).In the absence of brines, and excepting peralkaline melts, chlorine is strongly partitioned into an aqueous phase, and so chlorine isotope ratios should retain the signature of the source because isotope . There are two principal stable isotopes, 35 Cl (75.77%) and 37 Cl (24.23%), found in the relative proportions of 3:1 respectively, giving chlorine atoms in bulk an apparent atomic weight of 35.5.
