What is the name of the element that is used to describe chlorine?
This term was later used as a generic term to describe all the elements in the chlorine family (fluorine, bromine, iodine), after a suggestion by Jöns Jakob Berzelius in 1826.
How many isotopes of chlorine are there?
Chlorine has two stable isotopes, 35 Cl and 37 Cl. These are its only two natural isotopes occurring in quantity, with 35 Cl making up 76% of natural chlorine and 37 Cl making up the remaining 24%. Both are synthesised in stars in the oxygen-burning and silicon-burning processes. Both have nuclear spin 3/2+ and thus may be used for nuclear magnetic resonance, although the spin magnitude being greater than 1/2 results in non-spherical nuclear charge distribution and thus resonance broadening as a result of a nonzero nuclear quadrupole moment and resultant quadrupolar relaxation. The other chlorine isotopes are all radioactive, with half-lives too short to occur in nature primordially. Of these, the most commonly used in the laboratory are 36 Cl ( t1/2 = 3.0×10 5 y) and 38 Cl ( t1/2 = 37.2 min), which may be produced from the neutron activation of natural chlorine.
Why is chlorine used in swimming pools?
Several catastrophic collapses of swimming pool ceilings have occurred from chlorine- induced stress corrosion cracking of stainless steel suspension rods .
