2. What charge does the Sulfate SO4 ion carry?

  • 2-
  • 4-
  • 4+
  • 2+

3. What are Van Der Waals Forces?

  • any intermolecular force
  • electrostatic attraction between temporary dipoles and induced dipoles caused by movement of electrons in atoms and molecules.
  • shared pair of electrons
  • ionic attraction

4. How do the delocalised electrons in metallic bonding effect the melting point?

  • They make the bonding between atoms weaker
  • Because the shared pair of electrons create a strong intermolecular force
  • The more electrons there are, the stronger the bonding will be and the higher the meling point because the positive metal ions will have more electrons to be attracted to
  • They make the melting point lower because it stops the positive ions being attracted togther

5. What affects ionisation energy?

  • distance from the nucleus, shielding and intermolecular forces
  • nuclear charge, distance from nucleus and sheilding
  • the shape and size of an atom
  • only nuclear charge
