Xenon reacts with fluorine to form XeF2 which can be isolated before it reacts with fluorine to form XeF4. The linear configuration of XeF2 with the 2.00-A bond length and the vibrational force constants support the assignment of 10 electrons to the valence shell of xenon. Similar arguments support the assignment of 12 and 14 valence electrons respectively to xenon in XeF4 and XeF6.
