Electron Density vs Shape?

Postby Elena Maneffa 1E » Tue Nov 20, 2018 11:43 pm

What is the difference between electron density and shape? Why do we find two different names for the same molecule?

Electron density includes both lone pairs and bonding electrons. Accounting for all the areas of electron density gives you the molecular orbital geometry. VSEPR geometry only accounts for the bonded electrons.

Electron density is about the forces of the bonding and lone pairs and how they repel each other. Electron density determines the shape. There atomic structure tells us the shape of the electron densities, but the molecular shape, which is what we mainly focus on, is the structure of just the atoms and not the lone pairs.

Electron density refers to any regions that have electrons or atoms. This helps determine the overall structure. However, when identifying the molecular shape with regards to VSEPR, only the atoms are taken into account.

Electron density refers to all regions that have electrons, which includes lone pairs. However, when we name shapes, only atoms are counted.

Electron density is given by all regions that have electrons, including both lone pairs and bonded atoms. However, the molecular geometry refers only to the atoms that are bonded to the central atom.
