  • ionic bonding
    • ionic compounds are formed when ions either lose electrons to become positively  charged ions or gain electrons to become negatively charged ions.
    • ions achieve a full outer shell, with the electronic structure of a noble gas(group 0)
    • ionic bonds are strong forces of attraction between oppositely charged ions.
    • ionic compounds are solids at room temperature.
    • metal -- positive ions                                                                      non-metals -- negative ions.
    • ionic substances in aqueous solution can be extracted because the ions are free to move in water
