ionic bonding

Cards (7)

  • What is an ion?
    A charged atom or molecule that has lost or gained electrons
  • What charge do all metal ions form?
    Positive (as they always lose electrons)
  • What does reduction mean in terms of electron transfer?
    Gain of electrons (OIL RIG)
  • What does oxidation mean in terms of electron transfer?
    Loss of electrons (OIL RIG)
  • How do we write the symbol for electrons in an ionic half-equation?
    e-
  • What are the key features of an ionic dot and cross diagram?
    The (outer) shells of ions are filled in so they have full outer shells
    The ions are surrounded by square brackets []
    The ionic charge is on the top right (e.g. 2+)
  • What is an ionic bond?
    An electrostatic attraction between two oppositely-charged ions, that form when electrons are transferred.
