Can you determine the shape of a molecule if you're only given the AXE formula?

An AXE would have to have linear shape because an AXE is implying that there are only two atoms in the molecule thus not being able to create anything other than linear.

If by "AXE formula" you mean VSEPR formulas in general then yes in most cases since the VSEPR formula tells you the number of atoms attached to the central atom as well as the number of lone pairs atttached, and you can determine the name of the shape by the position of bound atoms. Molecules with the same formula generally have the same shape.

I believe Dr. Lavelle said that molecules with the same AXE formula have the similar molecular shape so yes. For Example AX4 is usually tetrahedral and AX2E1 is usually trigonal pyramidal

The AXE formula is quite helpful in determining the shape of a molecule and the shortcuts Dr. Lavelle taught us is even more helpful.

The only problem with this is molecules with double bonds can have the same formula as those with no double bonding, so they would still have the same shape and angle, but the single bonded molecule would be able to rotate while the double bonded molecule could not
