So, for a steric number of four, we get the Sp3 hybridization on the xenon atom in the XeO4 molecule. Start by drawing the compound's Lewis structure. In the XeO4 lewis structure, the central atom is xenon which is surrounded by 4 double bonds means 16 bonding electrons, hence, its valence shell is holding more than 8 electrons which violates the octet. )of each atom present in the compound (but take valence . Further, the extent of repulsion is also regulated by the difference in electronegativity of the central atom and other atoms participating in the formation of the molecule. How Do You Assign Formal Charges In A Lewis Dot Structure. So, all oxygen atoms in the above structure completed their octet, because all of them have 8 electrons(6 electrons represented as dots + 2 electrons in every single bond) in their valence shell. The electrons present in the outermost shell of an atom are referred to as its valence electrons. XeO4 is a non-polar molecule as the four oxygen atoms are arranged around the Xenon atoms in a tetrahedral fashion, symmetrically opposite to each other, therefore, canceling the charges. Please find enclosed a list of all necessary books and equipment. What are unbonded pairs of electrons? 4 F atoms will add 4 electrons to make 4 Xe-F bonds. I 2.
