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 ...
The atomic mass varies between 35.446 and 35.457 u, corresponding to the fluctuations in the isotopic composition of natural chlorine. All other chlorine isotopes are radioactive and decay with half-lives of less than 1 hour.
Element Chlorine (Cl), Group 17, Atomic Number 17, p-block, Mass 35.45. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
C) the atomic weight is the average of mass of all isotopes of chlorine atoms and found below the symbol on the periodic table. The atomic number is the number of protons in all chlorine atoms and is found on the top of the symbol in the periodic table.
This table shows information about naturally occuring isotopes, their atomic masses, their natural abundances, their nuclear spins, and their magnetic moments. Further data for radioisotopes (radioactive isotopes) of chlorine are listed (including any which occur naturally) below.
For example, chlorine has two isotopes: 35 Cl and 37 Cl. But the relative atomic mass of chlorine is not 36. In any sample of chlorine, 75 per cent of the atoms are 35 Cl and the remaining 25 per...
The lighter isotope 35 Cl diffuses more rapidly in aqueous solutions, whereas the concentration of the heavier isotope 37 Cl is higher in halide minerals than in coexisting solutions. Chlorine isotopes also have been fractionated photochemically in the laboratory.
