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