electrolysis

• which groups are mostly involved in ionic bonding ?

  1,2 aand 6,7
• what is a posotive and negative ion called ?

  posotive - cathode negative - anode
• why do ions often have nobel gas electron structure ?

  nobel gas electron structure is a full outer shell which is very stable
• what is ionic bonding between ?

  metal + non metal
• when can ionic substances conduct electricity ?

  in aq or molten - charged ions can move freely carrying charge
• describe the structure of an ionic bond ?

  giant lattice
• ionic compounds have similar properties what are those properties ?

  -high mp and bp

  -can only conduct electricity when molten or in aq solution

  -giant lattice structure
• why cant you extract metals less reactive than carbon using electrolysis (aq)?

  because carbon would form instead of the metal
