ionic structures

• what is an ionic bond?

  strong electrostatic force of attraction between oppositely charged ions
• what is an ionic structure?

  lattice of oppositely charged ions held together by strong ionic bonds
• what are ionic compound?

  made of crystals

  each crystal is called a giant ionic lattice
• what is a cation?

  lose electrons

  positively charged
• what is an anion?

  gains electrons

  negatively charged
• what types of elements have ionic bonds?

  metal + non-metal
• what is the drawing of an ionic structure?

  1. 3D cube
  2. contains negative or positive alternating at corners
• why do ionic structures have high melting points?

  1. X has giant ionic structure
  2. with strong attraction between oppositely charged ions
  3. high amounts of energy required to overcome ionic bonds
• why do ionic structures not conduct electricity solid?

  1. X has giant ionic structure
  2. ions in fixed position
  3. ions can't move and current can't flow
• why do ionic structures conduct electricity aqueous?

  1. X has giant ionic structure
  2. ions are free to move and carry charge
• why are ionic structures soluble when polar?

  1. X has giant ionic structure
  2. attraction forces form between water and ions
  3. provides energy to break ionic bonds
• why are ionic structures brittle?

  1. X has giant ionic structure
  2. attraction forces are broken
  3. when layers of ions slide over each other
