KEY CONCEPTS:

A=represents the CENTRAL ATOM
X=represents the number of surrounding atoms
E=represents the number of unshared electrons surrounding the CENTRAL ATOM

2 Regions of High Density Electrons
AX2 - Linear

3 Regions of High Density Electrons

AX3 = trigonal planar
AX2E = Bent

4 Regions of High Density Electrons
AX4 = tetrahedral
AX3E = Trigonal pyramidal
AX2E2 = Bent

5 Regions of High Density Electrons
AX5 = Trigonal bipyramidal
