The central atom has lone-pair electrons. Xenon (Xe) is a main group 8 (noble gas) element, so it has 8 valence electrons. Step 3: Use VSEPR table to find the shape. Services, Using Orbital Hybridization and Valence Bond Theory to Predict Molecular Shape, Working Scholars® Bringing Tuition-Free College to the Community, Number of bonding electron pairs on central xenon atom = {eq}4 {/eq}, Number of non-bonding electrons on central xenon atom = {eq}4 {/eq}, Number of non-bonding electron pairs on central xenon atom = {eq}2 {/eq}. Xenon tetrafluoride (XeF4) - D4h Symmetry — ChemTube3D. We also need to check to make sure we only used the number of available valence electrons we calculated earlier (no more, no less). All these formations called as square planar. The following compound has a total of ____... What hybridization do you expect for the atom...
