WebAug 15, 2024 · One chlorine atom in a compound. The molecular ion peaks (M+ and M+2) each contain one chlorine atom - but the chlorine can be either of the two chlorine isotopes, 35 Cl and 37 Cl. The molecular ion containing the 35 Cl isotope has a relative formula mass of 78. The one containing 37 Cl has a relative formula mass of 80 - hence … WebPeriodic Table--Chlorine. Chlorine has 9 isotopes with mass numbers ranging from 32 to 40. Only three of these isotopes occur naturally: stable 35 Cl (75.77%)and 37 Cl (24.23%), and radioactive 36 Cl. The ratio of 36 Cl to stable Cl in the environment is about 700 x 10-15: 1 (Bentley et. al., 1986). 36 Cl is produced in the atmosphere by spallation of 36 Ar …

WebNov 21, 2024 · Atomic Mass of Chlorine. Atomic mass of Chlorine is 35.453 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of … WebJul 30, 2024 · The atomic mass of an element is the weighted average of the atomic masses of the naturally occurring isotopes of that element. \[0.7577 \left( 34.969 \,u \right) + 0.2423 \left( 36.966 \,u \right) = 35.453 \,u \nonumber \] The weighted average is determined by multiplying the percent of natural abundance by the actual mass of the …
