The A in the VSEPR Formula

Postby Tamera Scott 1G » Tue Nov 13, 2018 3:34 pm

I understand that there is no subscript for A when writing the VSEPR formula in the "AXE" form, but does it have a purpose for being included in the formula?

The A in the VSEPR model has an implied subscript 1 because it is the central atom. I think the purpose is to denote that central atom, but you don't need the superscript because it is implied.

The purpose of A is just to represent the central atom in the particular molecule that you are looking at.

A represents the central atom and there can only be one central atom so no subscript is needed

As mentioned above, A represents the central atom
X represents the number of bonded atoms
E represents the lone pairs attached to the central atom

Hope this helps :)
