• what are the symbols for electrons used in diagrams that show ionic bonding and what are the diagrams called?

  square brackets

  
• why are oppositely charged ions attracted?


  strong electrostatic forces attract each other
• advantage and disadvantage of a dot and cross diagram?

  adv-useful for showing how ionic compounds are formed

  disad-don’t show structure, size of ions or how they’re arranged
