A: Interpretation-  The Lewis structure of a compound also indicates the presence or absence of lone pairs of electrons, which provides information on the compound’s chemical reactivity and physical properties. Thus, in the solid, every $\ce{Xe}$ atom has 7 bonds to fluorine, with two that are more ionic. A: The chemical formula of the given compound has to be determined: Lewis dot symbols allow us to predict the number of bonds atoms will form, and therefore the stoichiometry of a compound. The electron structure that shows is called the Lewis Structure of XeF4. The solid phase appears to be more like clusters of $\ce{[XeF5+ F^{-}]}$ with the fluoride ions bridging two $\ce{XeF5+}$ centers. As each F is in the -1 oxidation state, it would follow that Xe is in the +5 oxidation state, You can also have ions such as XeF5+ or XeF5-. View Answer. Formal charge = (number of valence electrons on the neutral, uncombined atom) - (number of covalent bonds to the atom in the current structure) - (the number of unshared electrons [not pairs] on the atom in the current structure). This applies to all F atoms.
