Hello guys! Welcome to KEM KORNER!

This page, I hope, will help you obtain a deeper understanding and appreciation of basic and not-so-basic chemistry concepts. For those looking for entertainment, there will be bits of that here although I'm not so sure yet how I'll go about this "entertainment" thing. But I assure you that this blog will be filled with links, downloadables and test-yourself questions that will help you, in some way, improve your understanding of the world of chemistry.

Suggestions, contributions and reactions, violent or otherwise, are also welcome... :)

The VSEPR Theory

The VSEPR (Valence Shell Electron Pair Repulsion) Theory is a simple technique used for predicting the shape or geometry of simple covalent molecules. It assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom.
The following video clip enumerates the different types of molecular structures. Blue represents the central atom, white represents the atoms bonded to the central atom, and red represents lone electron pairs (pairs of nonbonded electrons in the central atom.)


Thanks to starjester1 for the clip... :)
