Hi blackdice, i wish i could explain to you but this is really at its fundamental and it might take a long page and time. Always try google especially on ions, charges, ionic compound, try to answer some of them and we can work off from there.

1.Metals form positive ions, due to the fact they need to give electrons away to achieve a full outer shell.

2. ionic bonds are held together due to the electrostatic attraction of a positive metal ion and a negative non-metal ion. (opposites attract)

3. Fe3+ and Fe2+ are the two iron ions.

All I can remember. Hope it helps.
