first, identify the central atom and its valence electrons. Then, add an electron for each bonding atom, and add or subtract for the charge (- or +) to get the total number of electrons. Divide the total by 2 to find the total number of electron pairs and use that to identify the basic VSEPR shape.

I see. Are they considered equivalent due to a rule that explicitly states this? Thanks in advance.
