Any element Period 3 and down (the table) can take more than 8 electrons. In a trigonal bipyramidal electron-pair geometry, lone pairs always occupy equatorial positions because these more spacious positions can more easily accommodate the larger lone pairs. Copyright © 2021 Pathfinder Publishing Pvt Ltd. So that takes up 28 electrons, leaving us with 26 electrons, so we can add 24 electrons as lone pairs to … I. hybridized and contains 3 lone pairs and 2 bonding pairs of valence electrons around the Iodine. This discussion on The number of lone pairs (TOTAL) of electrons on the central atom in I3-, ClF3 and CIO3-are:Correct answer is '6'. so we've used all 22 of the valence electrons that we had available and it's kind of strange structure so let's check or formal charges just to make sure that we have the best Lewis Structure for I3-. Trigonal Pyramidal - 107.5 degrees It has 3 bonds and one lone pair. In the next structure, each lone pair is at 90° to 3 bond pairs, and so each lone pair is responsible for 3 lone pair-bond pair repulsions. Best Answer . Steric Number Calculation Examples .
