Homework 4.13
The question asks you to draw the shape of I3-. So I made the shape and saw that it was linear however the central atom had 6 lone pairs. Since the atom had lone pairs i figured that the shape would no longer be linear and that the shape would be bent. But the answer says linear with bond angles of 180. Can anyone explain to me why the lone pairs are not changing the shape of the structure? Thank you :)

Re: Homework 4.13
the only way that it would be bent if the central atom had two lone pairs. with three long pairs you can kinda picture it like a trigonal bipyramidal, the three lone pairs are 120 degrees from one another leaving the two other atoms being directly across from each other (180 degrees)

Re: Homework 4.13
is is a little bit confusing, but essentially there are 5 regions of electron density with the lone pairs having the most repulsion from each other. This means those three regions will make the trigonal planar aspect of a trigonal bipyramidal geometry, and the the Iodine forming a linear shape.
