Question

The numbers of lone pair(s) on xe in xef2 and xef4 are, respectively,

Answer 1

Explanation:

In XeF₄,total number of valence electrons of Xe=8,4 electrons are shared with 4F atoms ,4 electrons are left hence 2 lone pairs. In XeF₆,total number of valence electrons of Xe=8,6 electrons are shared with 6F atoms ,2 electrons are left hence 1 lone pair

Answer 2

hey...In XeF₄,total number of valence electrons of Xe=8,4 electrons are shared with 4F atoms ,4 electrons are left hence 2 lone pairs. In XeF₆,total number of valence electrons of Xe=8,6 electrons are shared with 6F atoms ,2 electrons are left hence 1 lone pair.
