To complete the octet of the fluorine atom, a fluorine terminal atom requires one valence electron. Xenon has eight outermost valence electrons, indicating that it possesses eight electrons in its outermost shell, whereas fluorine only has seven valence electrons in its outermost shell. The central atom is xenon, which is bordered on four terminals with four fluorine atoms( in square planar geometry), and two lone pairs of electrons on the xenon in the top and bottom of the square planar geometry. The net dipole moment of the XeF4 molecule is 0 D. The XeF4 molecule has a zero dipole moment due to an equal charge distribution of negative and positive charges. As a result, it has the zero dipole moment. But they canceled each other due to the symmetrical molecular geometry. It has a difference in electronegativity values between xenon and fluorine atoms, with xenon’s pull being less than fluorine’s terminal in the XeF4 molecule. The molecule of xenon tetrafluoride (with square planar molecular geometry) is tilted, the bond angles between xenon and fluorine are 90 degrees. The xenon tetrafluoride(XeF4) molecule is classified as a polar molecule. The xenon-fluorine bonds in xenon tetrafluoride(XeF4), for example, are polarised toward the more electronegative fluorine, and because both bonds have the same size and located around four fluorine terminals of the square planar with two lone pairs of electrons just out of the plan, their sum is zero due to the XeF4 molecule’s bond dipole moment and two lone pair of electron on the xenon atom. The geometry of the XeF4 molecule can then be predicted using the Valence Shell Electron Pair Repulsion Theory (VSEPR Theory), which states that molecules will choose the XeF4 geometrical shape in which the electrons have from one another.įinally, you must add their bond polarities to compute the strength of the Xe-F bond (dipole moment properties of the XeF4 molecule). The XeF4 Lewis structure is a diagram that illustrates the number of valence electrons and bond electron pairs in the XeF4 molecule. The first step is to sketch the Lewis structure of the XeF4 molecule, to add valence electrons around the xenon atom the second step is to add valence electrons to the four fluorine atoms, and the final step is to combine the step1 and step2 to get the XeF4 Lewis Structure.
