Why do ionic compounds form?

emilio asked the Naked Scientists:
   
Can you explain why ionic compounds are formed when a metal from the left side of the periodic table reacts with a non metal from right of the periodic table?

What do you think?

The metal donates electrons to the non metal to gain a full outer shell of electrons. It is the electrostatic forces between the oppositely charged ions that is the ionic bond.

Eg.

Mg must lose 2 electrons to get a full outer shell. O must gain 2 electrons to get a full outer shell.
So they form MgO.
