• what is the structure of ionic bonding?

  giant ionic lattice of oppositely charged ions, with strong forces of attraction in all directions
• why does ionic bonding have a high melting/boiling point?

  it is a giant ionic lattice with strong ionic bonds which requires a large amount of energy
• when doesnt ionic bonding conduct electricity?

  when solid because the ions can’t move
• does ionic bonding conduct electricity?

  only when dissolved in water because the ions are free to move and carry charge
• what is the structure of metallic bonding?

  a giant metallic lattice with positive metal ions surrounded by delocalised electrons
• metallic bonding consists of…

  metal atoms only
• does metallic bonding have a high melting point?

  yes because it is a giant metallic lattice with strong metallic bonding that requires a large amount of energy to break
• does metallic bonding conduct electricy?

  yes because it has delocalised electrons that can move through the structure and carry a charge
• can metallic bonding conduct thermal energy?

  yes because it has delocalised electrons that can move through the structure and transfer energy
• why is an alloy harder than a pure metal?

  in an alloy atoms are different sizes and layers are distorted
• explain the structure of simple covalent bonds

  simple covalent molecules with strong covalent bonds with weak intermolecular forces
• do simple covalent bonds have a high boiling point?

  no because they are a simple covalent molecule with weak intermolecular forces which require little energy to overcome
