## General Chemistry: Principles and Modern Applications (10th Edition)

Based on the number of electron pairs around I (the central atom), VSEPR notation suggests that the ions have different shapes. $\mathrm{ICl _{2}^{+}}$ (VSEPR notation, $\mathrm{AX}_{2} \mathrm{E}_{2}$ ) has a tetrahedral electron-group geometry and a bent molecular shape. $\mathrm{ICl _{2}^{-}}$ (VSEPR notation, $\mathrm{A} \mathrm{X}_{2} \mathrm{E}_{3}$ ) has a trigonal-bipyramidal electron-group geometry and a linear molecular shape.
