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 35.453(2) g/mol.[1]
Remarkably, solar neutrinos were discovered by an experiment using a radiochemical method based on chlorine-37 transmutation.[2]
