Chlorine (17Cl) has 25 isotopes, ranging from Cl to Cl, and two isomers, Cl and Cl. There are two stable isotopes, Cl (75.77%) and Cl (24.23%), giving chlorine a standard atomic weight of 35.45. The longest-lived radioactive isotope is Cl, which has a half-life of 301,000 years. All other isotopes have half-lives under 1 … See more Trace amounts of radioactive Cl exist in the environment, in a ratio of about 7×10 to 1 with stable isotopes. Cl is produced in the atmosphere by spallation of Ar by interactions with cosmic ray protons. In the subsurface … See more Stable chlorine-37 makes up about 24.23% of the naturally occurring chlorine on earth. Variation occurs as chloride mineral deposits have a slightly elevated chlorine-37 balance … See more • Chlorine isotopes data from The Berkeley Laboratory Isotopes Project's See more WebThe molecular weight of chlorine is 35.45 u. This is calculated from the natural abundance of 35 Cl (75%) and 37 Cl (25%). The natural abundance of these two isotopes is observed in the mass spectrum as two peaks separated by m/z 2 with a relative intensity of 3:1.
