ionic bonding

• ionic compounds are giant ionic lattices and consist of alternating anions and cations held together by strong electrostatic forces
• to melt/boil you need to separate the ions, held together by strong electrostatic forces, so they have high melting/boiling points
• if an ionic compound has a greater charge it will be attracted more strongly
• conductivity of ionic compounds

  
  

  when solid, the ions are not free to move so can't conduct electricity but when molten or aqueous (if soluble) the ions are free to move so can conduct electricity
• An ionic bond is the electrostatic attraction between cation and an anion.
• how are ionic bonds formed

  Ionic bonds are formed when a metal atom transfers one or more electrons to a non-metal atom, creating oppositely charged ions (cations and anions) that are held together by strong electrostatic forces.
