Ionic Compounds

• What is the structure of an ionic compound?

  • A giant lattice structure with ions arranged in a repeating pattern
  • Held together by strong electrostatic forces
  • These forces act in all directions, making ionic compounds very stable

  
• What are the properties of ionic compounds?

  • High melting and boiling points due to strong electrostatic forces
  • Conduct electricity only when molten or dissolved (ions are free to move and carry charge)
• Why are ionic compounds brittle?

  When layers of ions shift, like charges repel, causing the structure to shatter
• Why are ionic compounds often soluble in water?

  Water molecules can separate the positive and negative ions, allowing them to dissolve
