What is ionic bonding?

the transfer of electrons that leads to strong electrostatic forces of attraction between oppositely charged ions

What are the properties of ionic compounds?

  • high melting/boiling point

  • can conduct electricity

  • brittle (layers move across each other)

  • they dissolve in water

8
New cards

Why can ionic structures dissolve in water?

water has a slight electrical charge so the can attract ions away from lattice

9
New cards

How do they conduct electricity?

  • they don’t when solid since ions are in a fixed position

  • when molten they conduct electricity as the ions are free to move around (mobile) and carry charge
