To take full advantage of this page, you'll need to get the free LiveMath plugin.

I have more information about the LiveMath plugin on a separate page.

Even if you do not wish to get the plugin, you can still view the image animations. These animations will help you see the overlay of the atoms and central atom lone pair electrons over the trigonal planar geometry. Here are the definitions for the column headers-

• # BG: number of bonding groups about the central atom
• # LP: number of lone pairs about the central atom
• Shape: molecule's shape

Trigonal Planar Geometry (3 Electron Groups)
# BG	# LP	Shape	Animation
3	0	Trigonal Planar
2	1	Bent
1	2	Linear

 

Tetrahedral Geometry (4 Electron Groups)
# BG	# LP	Shape	Animation
4	0	Tetrahedral
3	1	Trigonal Pyramidal
2	2	Bent
1	3	Linear
