Whereas there are 2 electrons in the 5s orbital. The valence shell of an atom contains 6 electrons in a 5p orbital. Xenon tetrafluoride contains xenon as the central atom and it is the place where hybridization takes place. Fluorine atoms also pull the xenon atom towards them in opposite direction and with the same amount of force. The lone pair pulls xenon atoms towards them at equal force. Fluorine atoms are in the perpendicular plane on the x-axis.

The lone pairs are present in the plane on the y-axis. Imagine a plane on the y-axis perpendicular to the plane on the x-axis. Between the central atom and its lone pair direction of the dipole moment will favor pointing to the lone pair. For dipole moment between Xenon and Fluorine, it helps us pull xenon towards fluorine because fluorine is more electronegative in nature. Dipole moment in XeF 4 :īy knowing the dipole moment helps to determine the position of atoms attached to the central atom is correct or not. Now after this we have to check the stability of xenon tetrafluoride the fluorine must follow the octet rule. Then we draw the remaining unpaired electrons of each atom according to their number of valence electrons. First of all, we draw single bonds between the central atom and terminals fluorine atoms. In xenon tetrafluoride, the xenon is a less electronegative atom so it is considered a central atom.

The electronic configuration of xenon tetrafluoride is ġs 2 ,2s 2, 2p 6, 3s 2, 3p 6, 4s 2, 3d 10, 4p 6, 5s 2, 4d 10, 5p 6

So xenon has 8 electrons and fluorine has 7 electrons so the total number of electrons is 36 electrons. And from the periodic table, we get the valence electrons of each atom. AS we know that in xenon tetrafluoride there is 1 xenon and four fluorine. First of all list down the atoms present and the total number of atoms in the compound. This can be given out by sum up of valence electrons of each atom in the compound.
