VSEPR Theory & Shapes - Year 12 Recap

The VSEPR Theory explains that regions of electron density (bonding pairs and/or lone pairs or electrons) will repel each other. This gives molecules and ions their characteristic shapes.

In Year 12, we explored examples with 2, 3 or 4 regions of electron density. These videos and notes are a summary of those three examples:

Two Regions of Electron Density

Three Regions of Electron Density

Four Regions of Electron Density
