Electrons left in the valence shell when Xe is converted to XeF6 is

Electronic configuration of Xe : [Kr] 4d¹⁰ 5s² 5p⁶.

Xe has 8 valence electrons and It shares these six electrons with six F atoms to form six Xe-F sigma bonds.

Thus, the electrons left in the valence shell are 2.

Final answer : Hence the correct answer is 2 .
