![]() ![]() 3)ġ) Quantity Percentage of natural occurrence.Ģ) Gyromagnetic ratio: 10 7 rad T -1 s -1 Quadrupole moment: Q fm -2Īccording to the Radiation Protection Ordinance (StrlSchV 2018, Germany), the following values (columns 1 to 7) apply to the handling of Chlorine radionuclides: Nuclide NMR active Chlorine nuclides Nuclide quantity 1) spin unlisted-: Nuclides that have already been mentioned in the literature but for some reason can no longer be found in the current nuclide tables because their discovery e.g. ~ - Theoretical values or systematic trends. ()- Numbers in brackets: uncertainty to represent the spread of the reported value. If applicable, the corresponding decay modes can be found in the data for the respective starting nuclide.Ĩ - decay: half-live of the Chlorine isotope (a = years d = days h = hours min = minutes s = seconds).ĩ - decay mode: type of decay into the respective daughter nuclides with n = neutron emission p = proton emission α = alpha decay β - = beta minus decay with electron emission EC = electron capture β + = positron emission ε = β + and/or EC Iso = isomeric transition CD = cluster decay SF = spontaneous decay.ġ1 - decay energy Particle energy related to decay type.ġ2 - other information and notes: AL = Adopted Levels (link to external data ). In addition, the mass excess is given in MeV.Ħ - source nuclides: Possible, assumed or actual source nuclides (mother nuclides, parent nuclides). Further information on the individual Chlorine isotopes is listed on separate pages and can be accessed via the link in column 1.ġ1 28.02954(64) u Ģ - E: isotope symbol with mass number (superscript number of nucleons) and atomic number (subscript number of protons).Ĥ - relative atomic mass of the Chlorine isotope (isotopic mass including electrons) and the mass of the atomic nucleus in square brackets (nuclear mass, nuclide mass without electrons), each related to 12C = 12.00000. Isotope Table: ChlorineThe two following tables list the most important data and properties of the Chlorine isotopes. The atomic mass varies between 35.446 and 35.457 u, corresponding to the fluctuations in the isotopic composition of natural chlorine.Īll other chlorine isotopes are radioactive and decay with half-lives of less than 1 hour. ![]() Natural chlorine deposits are composed of the stable isotopes chlorine-35 and chlorine-37 in a 3:1 ratio and traces (7 x 10 -13 atoms to 1 stable chlorine atom) of the radioisotope chlorine-36 together the latter is mainly produced by the effects of cosmic radiation on 40Ar and 36Ar and radioactively decays to 36Ar and with a half-life of 308000 years 36p. The individual nuclides differ in the number of neutrons in the atomic nucleus What all Cl isotopes have in common is the number of protons and - in the uncharged, neutral state - of electrons: 17. 24 isotopes and some nuclear isomers of the chemical element chlorine are known. ![]()
