Bonding describes the forces that hold atoms to other atoms in elements or molecules. Bonding also describes the forces that attract molecules to other molecules in molecular compounds or ions to each other in ionic compounds.

Where do forces originate anyway. Let Brian Cox explain.

Physicist Brian Cox has two jobs: working with the Large Hadron Collider at CERN, and explaining big science to the general public.

Now read pagers 79-82 in the Wignall and Wales text book. Try exercise 9A then 9B
