ionic bonding

here's some detail on ionic bonding, it would've been better if I could draw diagrams. oh well

hope it helps :D

  • Ionic bonding
    • in ionic bonding, atoms lose or gain electrons to form charged particles (ions) which are then strongly attracted to one another (attraction of opposite charges)
      • Groups 1&2 and 6&7 are the most likely to form ions
        • Group 1 and 2 elements are metals and they lose electrons to form positive ions.
        • Group 6 and 7 elements are non-metals. They gain electrons to form negative ions.
    • a useful way of presenting ions is by drawing out their electronic structure. By using square brackets and + or - to show the charge.
    • remember, the + and - charges e.g. Na+ for sodium, just tell you what type of ion the atom will WILL FORM in a chemical reaction.
      • In sodium metal there're only neutral sodium atoms, Na. the Na+ ions will only appear if the sodium metal reacts with something like water or chlorine.
