Other questions in this quiz

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

  • They make the bonding between atoms weaker
  • 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
  • Because the shared pair of electrons create a strong intermolecular force

3. What are Van Der Waals Forces?

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

4. What are three characteristics that ionic compounds have (when in a giant ionic structure)?

  • always conducts electricity, low boiling point, cannot dissolve in water
  • conduct electricity when molten or dissolved, have high boiling points, dissolve in water
  • dissolve in water, low boiling point, can not conduct electricity
  • high boiling point, always conducts electricity and cannot dissolve in water

5. What is a covalent bond?

  • a shared pair of electrons
  • the electrostatic attraction between two oppositely charged ions
  • 1 shared electron
  • the electrostatic attraction between ions with the same charge
