This is a negative ion with more electrons than protons 6 of 12 what is relative isotopic mass? the mass of an isotope relative to 1/12th of the mass of an atom of carbon-12 7 of 12 what is relative atomic mass? this is the weighted mean mass of an atom of an element relative to 1/12th of the mass of an atom of carbon-12 8 of 12 what does the weighted mean mass take into account? 1. percentage abundance of each isotope 2.relative isotopic mass of each isotope 9 of 12 how do you determine relative atomic mass? mass spectrometer 10 of 12 what are the four steps of mass spectrometry? print 11 of 12 what are the five main ions that we need to know? Ammonium NH4+, hydroxide OH-, nitrate NO3-, carbonate CO32- and sulphate SO42- 12 of 12
