VSEPR formula for molecules of the same atom

Postby EMurphy_2L » Mon Nov 11, 2019 9:48 pm

What is the VSEPR formula for I3- ?
Also, there are three lone pairs on the central atom I so what would the formula be?

The VESPR for I3- would be treated the same way as other molecules.
It would be in the form AX2E3, which will make it a linear molecule as the lone pairs would go in the equatorial domains.

I believe that I read in the textbook that the VSEPR formula for molecules of the same atom result in a linear shape.

In this case it does result in a linear formula but O3 would be bent, so that is not a rule.
