VSEPR calculation for perchlorate, [ClO4]-

Perchlorate, [ClO4]-
Lewis structure: ClO4anion.gif
Central atom: chlorine
Valence electrons on central atom: 7
4 terminal oxygens each contribute 1 electron in the four σ bonds 4
Subtract four for the four electrons contributed by Cl to the four π bonds (one for each): -4
Add one for the negative charge located on Cl 1
Total: 8
Divide by 4 to give electron pairs 4
4 electron pairs: tetrahedral geometry for the four shape-determining electron pairs
ClO4anion
