8(a) The relative atomic masses of elements can be determined using a mass spectromete(i) Define the term relative atomic mass.(3___(i) Describe fully how positive ions are formed from gaseous atoms in a mass spectrometer(II) The following dat a were obtained from the mass spectrum...
Chlorine, for example, has an atomic mass value of 35.453 u, while copper has one of 63.54 u. These values of the atomic masses can be explained by the effect of the relative abundances of the isotopes of the elements contributing to produce the observed net mass. If an element consists ...
