Strucuture and bonding

  1. 2. Powerpoint Templates Covalent & Ionic Compounds: Structure & physical properties
  2. 3. Structure of Ionic Compounds <ul><li>Crystal lattices </li></ul>
  3. 4. Physical Properties of Ionic Compounds
  4. 5. Physical Properties Ionic Compounds States (at room temperature) Solid Electrical conductivity Solid: No   Liquid: Yes   Aqueous: Yes (if soluble) Boiling point and Melting Point High Solubility in water Often high Thermal conductivity Low
  5. 6. COVALENT COMPOUNDS: MOLECULES <ul><li>Silicon </li></ul>
  6. 7. Covalent Compounds; Macromolecules Diamond
  7. 8. Physical properties
  8. 9. Physical properties Covalent compounds States (at room temperature) Solid, liquid, gas Electrical conductivity Usually none Boiling point and Melting point Varies, but usually lower than ionic compounds Solubility in water Varies, but usually lower than ionic compounds Thermal conductivity Usually low
