This is because chlorine contains two different isotopes, chlorine … WebJun 26, 2024 · The atomic weight is calculated by adding the mass of each isotope multiplied by its fractional abundance. For example, for an element with 2 isotopes: atomic weight = mass a x fract a + mass b x fract b. If there were three isotopes, you would add a 'c' entry. If there were four isotopes, you'd add a 'd', etc.

WebThe isotopic ratios of commonly encountered elements are summarized in Table 6.1. In Table 6.2, the ratios have been normalized to the most abundant isotope to illustrate the expected peak ratios in a mass spectrum. Compounds containing one chlorine have a [M + 2] peak that is one third the size of the molecular ion (Figure 6.5a).
