1. Compound is dissolved in solution, ionised by a high voltage supply (to mostly 1+ ions), accelerated by a negatively charged plate, becomes a beam of ionised molecules, reach detector and cause a current to flow
2. Time of flight used to work out m/z value and plot graph
Stages of mass spectrometry: ionisation, acceleration, detection
First ionisation energy: the energy required to remove 1 mole of electrons from a mole of gaseous atoms to form 1 mole of gaseous 1+ ions
Relative atomic mass = average mass of atom / 1/12 mass of carbon-12
Complete the definition for: Relative atomic mass
A) Average mass of atom
B) 1/12 the mass of carbon-12
Why do isotopes have the same chemical properties?
same electronic configuration
How is relative abundance determined in a mass spectrometer?
the positively charged isotopes hit the detector and gains an electron and the current produced is used to determines the abundance of that ion
