Atomic Weights and Isotopic Compositions for Chlorine
Web26 de nov. de 2024 · Atomic mass of Chlorine is 35.453 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams. WebChlorine ( 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 (75.77%) and 37 Cl (24.23%), giving … Web"The atomic mass of chlorine- 35 is 34.97u, and the atomic mass of chlorine- 37 is 36.97u. And yet, if you look on the periodic table, you'll find that the mass of chlorine is given as 35.45u. Where does this number come from?"
