# How to know which atom is the central atom in VSEPR theory?

How to find the central atom? What is the central atom in $\ce{PCl3}$ and how to find the shape using VSEPR theory?

• You don't really have to look for the central atom. Technically, VSEPR theory may be applied to any atom in the molecule, only in case of chlorines it would not produce anything useful. Apr 5 '16 at 21:08
