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-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]
The most stable chlorine radioisotope is 36 Cl. 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 ...

These 35 radioactive naturally occurring nuclides comprise the radioactive primordial nuclides. The total number of primordial nuclides is then 251 (the stable nuclides) plus the 35 radioactive primordial nuclides, for a total of 286 primordial nuclides. This number is subject to change if new shorter-lived primordials are identified on Earth.
Elliott made all three extra points and was successful on both field goals (of 35 and 33 yards) against Kansas City in the Super Bowl. Harrison Butker has stayed at the top his game for Kansas City.
