properties of ionic compounds

• Why do ionic compounds have high melting and boiling points?

  Strong electrostatic forces require much heat energy
• Why can't ionic compounds conduct electricity when solid?

  The ions are locked in place by attraction
• When can ionic compounds conduct electricity?

  When molten or dissolved in water
• What is the electronic structure of sodium and chloride ions after bonding?

  Both have a full outer energy level
• What is the compound formed from sodium and chlorine?

  Sodium chloride
• What is a giant ionic lattice?

  A structure where positive and negative ions alternate
• What holds the ions in a giant ionic lattice together?

  Strong electrostatic forces of attraction
• What are ionic bonds also called?

  Electrostatic forces of attraction
• How do ionic compounds behave when heated?

  Particles vibrate until the solid melts
• What is the melting point of sodium chloride?

  Around 800°C
• Why do ionic compounds require a lot of heat energy to melt?

  Because of strong electrostatic forces
• What is the difference between solid and molten ionic compounds in terms of conductivity?

  Solids cannot conduct; molten can conduct
• What carries the electrical charge in molten ionic compounds?

  The moving ions
