WebAbout one quarter of all chlorine atoms have 20 neutrons, giving those atoms a mass number of 37. Were you to simplycalculate the arithmetic average of the precise atomic masses, you would get approximately 36. 34.969+36.966 2 =35.968 As you can see, the average atomic mass of chlorine is 35.453 which is significantly lower. Why? WebThe chlorine isotopes of those compounds may also be fractionated by biochemical degradation reactions. Chlorinated solvents are reported to have δ ( 37 Cl) values ranging from at least −6.0 ‰ to +4.4 ‰, corresponding to x ( 37 Cl) = 0.2411 to 0.2430 and Ar (Cl) = 35.450 to 35.454.

WebChlorine-36 is produced in the atmosphere by cosmic-ray spallation of 40 Ar ( Lal and Peters, 1967 ). It decays to 36 Ar with a half-life of 301,000±4,000 yr ( Bentley et al., … WebPROBLEM 2.3. 4. Average atomic masses listed by IUPAC are based on a study of experimental results. Bromine has two isotopes, 79 Br and 81 Br, whose masses (78.9183 and 80.9163 amu) and abundances (50.69% and 49.31%) were determined in earlier experiments. Calculate the average atomic mass of Br based on these experiments. 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.
