Chlorine (17 Cl) has 25 isotopes, ranging from 28 Cl to 52 Cl, and two isomers, 34m Cl and 38m Cl. There are two stable isotopes, 35 Cl (75.8%) and 37 Cl (24.2%), giving chlorine a standard atomic weight of 35.45. The longest-lived radioactive isotope is 36 Cl, which has a half-life of 301,000 years. All other isotopes have half-lives under 1 ...
Chlorine-35 (Cl-35 or 35 Cl), an isotope of chlorine This page was last edited on 26 November 2022, at 07:44 (UTC). Text is available under the Creative Commons ...
The primary decay mode of isotopes lighter than 35 Cl is electron capture to isotopes of sulfur; that of isotopes heavier than 37 Cl is beta decay to isotopes of argon; and 36 Cl may decay by either mode to stable 36 S or 36 Ar. [42] 36 Cl occurs in trace quantities in nature as a cosmogenic nuclide in a ratio of about (7–10) × 10 −13 to 1 ...
This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.
Chlorine-37 (37 Cl), is one of the stable isotopes of chlorine, the other being chlorine-35 (35 Cl). Its nucleus contains 17 protons and 20 neutrons for a total of 37 nucleons. Chlorine-37 accounts for 24.23% of natural chlorine, chlorine-35 accounting for 75.77%, giving chlorine atoms in bulk an apparent atomic weight of 35.45(1) g/mol. [1]
A total of eighteen isotopes of fluorine have been discovered, with atomic masses ranging from 13 to 31. Chlorine has two stable and naturally occurring isotopes, chlorine-35 and chlorine-37. However, there are trace amounts in nature of the isotope chlorine-36, which occurs via spallation of argon-36. A total of 24 isotopes of chlorine have ...

For example, the relative atomic mass of chlorine is 35.453 u, which differs greatly from a whole number as it is an average of about 76% chlorine-35 and 24% chlorine-37. Whenever a relative atomic mass value differs by more than ~1% from a whole number, it is due to this averaging effect, as significant amounts of more than one isotope are ...
