Electron density in molecules

Molecules are held together as a result of a delicate balance between repulsive (nucleus-nucleus) and atractive (nucleus-electron) forces. The distribution of electrons around the molecule is crucial to determine its properties.

Below there is a plot of the distribution of electron density around a molecule comprising a metal center and five water molecules (one of them hydrogen bonded).

The blue lines represent the highest electron density and the red lines the lowest.
