16VSPER- Valence Shell Electron Pair Repulsion
VSPER is used to describe the ____________ ___________ of molecules
Single, double, or triple bonds act ________________.
Unbonded electrons, ___________ ______________ of electrons take up more space than bonded
pairs of electrons.
Electron densities (lone pairs and bonds) will arrange themselves _____________ around an atom to
minimize repulsive forces.
Steps to determine geometry:
1. Draw the Lewis Structure
2. Count up the number of bonds on the central atom.
3. Look on the chart to find the shape (You will NOT have the chart on the test).
