### AXE Notation and Shape

On Friday we learned that AX4E corresponds to the see-saw shape, etc. Is the AXE notation an identifier for every possible molecular shape? Additionally, are double/triple bonds taken into account when writing the AXE notation?

For me, it also helped to know the amount of lone pairs/bonding atoms that each shape had. For example, the seesaw shape has 4 bonded atoms and 1 lone pair on the central atom, for a total of 5 atoms total in the molecule.

Yes, the AXE notation will tell you the molecular structures.

The number of single/double/triple bonds are not taken account in the AXE notation. All that is considered is the number of atoms bonded around the central atom (whether that be single, double, triple) denoted by X, and the number of lone pairs denoted by E.

Orher than knowing how to write the AXE notation are there any other ways we could be tested on this concept on the final?
