Ionic compounds

• Ionic compounds


  • Giant conic couryounde structure
  • Oppositely charged ions arranged in a regular way
  • Forms crystals
  • Overall has no net charge
• Solubility of ionic compounds

  Most are soluble in polar solutions, e.g. water
• Electrical conductivity of ionic compounds

  • As a solid, they do not conduct electricity because the ions are fixed in position by ionic bonds
  • When dissolved in water (aqueous) or molten, the ionic bonds are broken and the ions are free to move, so the solution/liquid can conduct electricity
• Ionic compound


  A type of chemical compound formed by the electrostatic attraction between oppositely charged ions
• Ion


  An atom or molecule that has a net electric charge due to having gained or lost one or more electrons
• Cation


  A positively charged ion, formed when an atom loses one or more electrons
• Anion


  A negatively charged ion, formed when an atom gains one or more electrons
• Giant ionic lattice structure

  The regular arrangement of oppositely charged ions in an ionic compound, held together by electrostatic attraction
• Crystal


  A solid material with a regular arrangement of atoms, ions, or molecules
• Net charge


  The overall electric charge of a molecule or ion, calculated by adding up the charges of its individual components
• Cations have a positive charge because they have lost electrons, while Anions have a negative charge because they have gained electrons.
