1. 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

4. What is dative covalent bonding?

  • When there are less than 8 electrons in outer shell
  • When atoms share more than one pair of electron e.g. in N2

5. What is ionic bonding?

  • the intermolecular forces between induced dipoles
