Okay I apologise if you don't like the fonts etc. on the post before, I thought it would be fun but i'll tone it down a bit but I assure you it will still look fun!
Ionic compounds are held together by strong forces between oppositely charged ions, this is called Ionic Bonding.Ionic Bonding holds together oppositely charged ions in Giant Structures.
Above is an example of Ionic bonding Between a Sodium atom and a Chloride atom. As you can see they posses opposite charges. Sodium positive and the Chloride atom negative.
Then on the right we can see part of the Giant Structure or we can say part of the Giant Ionic Lattice. Throughout the Lattice or Structure strong forces of attraction act between the atoms.
Referring to the picture again on the left side there are diagrams of the atoms and below the positive or negative charge of its ions. Diagrams like these might be familiar to you! We can draw these diagrams using dot and crosses to represent atoms and ions like below:
It's also useful as we can see the gain, loss or sharing of the ions. As above shows that Sodium has lost one electron to get a full outer shell and Chloride has gained an electron to get a full outer shell.
I also recommend quickly checking out this BBC bitesize page http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/bonding/ionic_bondingrev1.shtml which has all about Ionic Bonding in more depth and etc...
