AS Chemistry - Ionisation Energies

HideShow resource information

Ionisation is the removal of electrons

  • O(g) -> O+(g)   + e-
  • O(g) -> O2+(g) + e-
    • The atom must always be gaseous

Factors affecting ionisation energy:

  • Nuclear charge
    • More protons means the nucleus is more positively charged, this causes a stronger attraction of electrons
  • Distance from nucleus
    • If electrons are closer to the nucleus,
