  1. 1Define the term 'ionisation energy'The energy required to remove one mole of electrons from 1 mole of gaseous atoms
  2. 2Name the four factors which affect ionisation energyDistance from nucleus, number of protons, shielding, paired electrons
  3. 3State how 'distance from nucleus' affects ionisation energyfurther away from nucleus means a weaker force of attraction
  4. 4State how 'number of protons' affects ionisation energyMore protons means more positive charge pulling on the electrons
  5. 5State how 'shielding' affects ionisation energyfull shells of electrons between the nucleus and outer shell reduce the attraction of the protons and outer electrons
  6. 6State how 'paired electrons' affects ionisation energyare easier to remove within the same sublevel than unpaired
  7. 7Define the term 'isotopes'atoms of the same element where there are the same number of protons but different number of neutrons
