Van Der Waals Bonding

This type of bonding is quite rare and very weak. It is found in organic compounds and in the crystallised forms of certain gases, like argon and neon.  Examples are sulphur, graphite, and gypsum.

In this diagram of Selenite atoms we see alternating layers of SO4 Tetrahedra, (blue), calcium (teal), and water (yellow). The bonds between these layers are very weak. This explains why selenite is so easy to scratch.  Incidentally, selenite atomic structure demonstrates how much of the planet’s water content is locked away in rocks and minerals beneath the ground.
