Ionic Bonding

Ionic Bonding

1. so an atom has a full outer shell

2. lose elctrons

3. gain electrons

4. becomes an ION

   • CATION= positice
     • metals
   • ANION=negative
     • non-metals
   • CHARGED PARTICLE

5. Metal + Non-metal

6. TRANSFER OF ELECTRONS

7. attraction between oppositely charged ions

8. ELECTROSTATIC ATTRACTIONS

9. IONIC COMPOUNDS

   • High melting and boiling point
     • lots of heat energy needed to separate strong electrostatic charges
   • soluble in water
     • water molecules collide with the ionic solid
     • collisions knock off ions
     • ions then diffuse evenly
   • conducts electricity when molten or solution
     • electrostatic charges are overcome
     • ions can move and carry current

10. ionic lattices
