VSEPR

Valence Shell Electron Pair Repulsion Theory!
VSEPR is the theory used to predict molecular shapes.  Because each region of electron density (lone pair, single bond, double bond, triple bond) is negatively charged, the regions of electron density repel one another as much as possible.  This repulsion dictates the shape of the molecule or polyatomic ion.  If you're having trouble visualizing these 3-dimensional shapes, try the PhET simulation we looked at in class:

Have a good weekend and don't forget to look at the OWL assignments that are currently posted.

    Thanks for info, it's rather hard to understand it, cause I was taught some another theory.
