Naming; VSEPR

Postby HanSitoy » Sun Nov 19, 2017 9:01 pm

I'm sorry, I understand that the sulfite ion has the shape of trigonal pyramidal, but can someone please explain why it is denoted as AX^5?

Thank you

The variables A and X stand for different things in the VSEPR model! Lavelle went over it in his lecture I am pretty sure, but you might be talking about some sort of exception.

A is used to denote the central atom
X denotes the bonded atom
E denotes the lone pair

This means that there is one central atom (A) and five atoms attached to the central atom (X^5). Since there is no E there are no lone pairs of electrons.
