Question

The number of lone pairs of electrons on xe atom in xef4 is

Answer 1

XeF4 has two lone pairs.As Xe has 8 electrons in its outermost shell and fluorine has 7 electrons in the outermost shell.Each fluorine atom shares 1 electron with Xe and hence the valence she'll of fluorine atom is complete.Hence Xe is left with 4electrons and it forms two lone pairs.
