Ionic Bonding

Structure and Bonding

Ionic Bonding:

• Ionic compounds are held together by strong forces of attraction between the oppisitley charged ions. This is called ionic bonding.
• Besides the elements in Group 1 and 7, other elements that can form ionic compounds include those from Groups 2 and 6.

The ionic bonds between the charged particles result in an arrangement called a giant ionic structure or giant ionic lattice. The force exerted by an ion on the other ions in the lattice acts equally in all directions. This is why the ions in a giant structure are held so strongly together. The giant structure is regular because the ions are all packed tightly together and are alternatley positive and negative.

Sometimes the atoms reacting need to gain or lose two electrons to gain a full outer shell, for example when Magnesium (2,8,2) reacts with Oxygen (2,6) it has to lose two electrons to gain a full outer shell and it…
