1. Electrical Conductivity and Models of Bonding
Electric current – Flow of Charge (+ or – ions or electrons).

MOVING ELECTRONS
MOVING IONS

2. Conductivity of metals – Moving electrons carry charge

3. nonElectrolyte, weak electrolyte, strong electrolyte solutions

4. COVALENTLY BONDED SUBSTANCES DON’T FORM IONS WHEN DISSOLVED IN WATER
NOTE: ONLY NEUTRAL MOLECULES PRESENT; NO FULLY CHARGED PARTICLES
NEUTRAL ETHANOL DISSOLVED IN WATER
NEUTRAL SUGAR MOLECULES DISSOLVED IN WATER

5. Solid salt – ionic lattice
IoNS LOCKED INTO POSITION BY MULTIPLE ELECTROSTATIC ATTRACTION
EACH ION IS BONDED TO 6 IONS OF THE OPPOSITE CHARGE

6. Molten sodium chloride is an excellent conductor
Moving ions free to move past each other

7. IONIC COMPOUNDS SEPARATE INTO IONS IN SOLUTION
WATER IS POLAR; IT HAS A PARTIALLY NEGATIVE OXYGEN SIDE AND PARTIALLY POSITIVE HYDROGEN SIDES THAT WILL ATTRACT IONS OUT OF THE LATTICE
