  1. 1Ionic bonds always produce giant ionic structures.
    1. AVerdadero
    2. BFalso
  2. 2Are the ions in giant ionic structures free to move? [blank_start]No[blank_end]
    Therefore, do giant ionic structures conduct electricity? [blank_start]No[blank_end]
    How strong are the chemical bonds between the ions? [blank_start]Very strong[blank_end]
    Are the chemical bonds strong between some or all of the ions? [blank_start]all[blank_end]
    [blank_start]Sodium chloride[blank_end] (aka salt) is one giant ionic [blank_start]lattice[blank_end]. This is why salt crystals tend to be cuboid in shape.
    1. ANo
    2. BNo
    3. CVery strong
    4. Dall
    5. ESodium chloride
    6. Flattice
  3. 3Do giant ionic lattices have high or low melting and boiling points? [blank_start]high[blank_end]
    This is due to the very strong [blank_start]ionic[blank_end] bonds between [blank_start]all[blank_end] the ions in the giant structures.
    1. Ahigh
    2. Bionic
    3. Call
  4. 4Which ionic compound dissolves in water to form a solution that conducts electricity? [blank_start]NaCl[blank_end] (write symbol equation)
    When dissolved the ions separate and are free to [blank_start]move[blank_end] in the solution, so they can carry electrical [blank_start]current[blank_end]. This cannot happen to all ionic compounds, Mg0 (magnesium oxide) is in[blank_start]soluble[blank_end].
    1. ANaCl
    2. Bmove
    3. Ccurrent
    4. Dsoluble
  5. 5Do giant ionic lattices conduct electricity when molten? [blank_start]yes[blank_end]
    When melted, the ions are free to move and will carry [blank_start]electrical[blank_end] current.
    1. Ayes
    2. Belectrical
  6. 6Ionic compounds form [blank_start]crystals[blank_end] which are giant ionic lattices.
    1. Acrystals
  7. 7Ions are [blank_start]charged[blank_end] particles
    1. Acharged
  8. 8In ionic bonding, atoms lose or gain [blank_start]electrons[blank_end] to form [blank_start]ions[blank_end]
    1. Aelectrons
    2. Bions
  9. 9Ions with [blank_start]opposite[blank_end] charges are strongly attracted to each other
    1. Aopposite
  10. 10Tick the correct statements:
    1. Ametals have low numbers of electrons in their outermost shell
    2. Bmetals form negatively charged ions
    3. Celements in group 7 gain electrons when they react
    4. Datoms form ions because they are more stable when they have full outer shells
    5. Eelements in group 8 are very reactive
