TOF steps - 1) ionisation 2) acceleration 3) ion drift 4) detection 5) analysis Electron impact - Sample vaporised and electron gun fires high energy electrons at it which knock off 1 electron from each particle, making them 1+ ions NB- can knock off more than one e or break molecular ion electrospray ionization - Sample dissolved in volatile solvent then injected through needle to give fine mist which is attached to positive end of high voltage power supply, particles gain proton ...

This question is about atomic structure.There is a general trend for an increase in ionisation energy across Period 3. Give one example of an element that deviates from this trend. Explain why this deviation occurs. : Aluminium / Al(Outer) electron in (3)p orbital / sub-shell (level) (3p) higher in energy / slightly more shielded (than 3s) / slightly further away (than 3s) Give an equation, including state symbols, to represent the process that occurs when the third ionisation energy of...
