Two orbitals of an atom having the same energy level fuse together to form a new kind of an orbital. Certain steps can be used to draw a perfect XeF4 Lewis structure. 27. Therefore, according to orbital overlap concept, formed by the end to end (hand-on) overlap of bonding the formation of a covalent bond between two atoms orbitals along the . Looking at the above Lewis structure for XeOF4 molecule, oxygen that had six valence electrons formed a double bond with Xenon, hence completing its octet. But lone pairs of electrons are significant in deciding many other properties like the shape of the molecule. Choice (A) omits the sigma bonds from the double bonds. Here, all the angles should be less than 90 due to the repulsion forces that exist between the lone pairs as well as bond pairs of different atoms. In the context of the XeF4 lewis structure, the central atom xenon has 4 electrons left after sharing one electron with 4 fluorine atoms.
