Nine lone pairs are there in i3-

9 because they are asking for 3 iodine

Hello. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

Iodine having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons. I3- is dsp3 hybridized and contains 3 lone pairs and 2 bonding pairs of valence electrons around the Iodine. The VSEPR predicts the linear shape.
