Listed below are the "best arrangements" of the regions of high electron density which minimize electron repulsion. You may click on any of these arrangements to examine them.
| # regions of high electron density | best arrangement | description |
| 2 | linear |
central atom and regions of high electron density arranged in straight line |
| 3 | trigonal planar |
regions of high electron density directed at the corners of an equilateral triangle |
| 4 | tetrahedral |
regions of high electron density directed at the corners of a tetrahedron |
| 5 | trigonal bipyramidal |
three regions of high electron density directed at the corners of an equilateral triangle/one region of high electron density directly above the plane of the triangle and one directly below the plane |
| 6 | octahedral |
regions of high electron density directed at the corners of an octahedron |
