SF6 Lewis structure there

are a total of 12 valence

electrons on the Sulfur atom.

Answer 2

SF₆ molecule is formed by one atom of Sulfur(S) and 6 atoms of Fluorine (F).

Sulfur occupies the sixteenth position in the modern periodic table and has 16 electrons. It has 2, 8, 6 configurations with 2 electrons in the K shell, 8 in the L shell, and 6 in the M shell. So, it has 6 valence electrons.

Fluorine occupies the ninth position in the modern periodic table and has 9 electrons. It has a 2, 7 configuration with 2 electrons in the K shell and 7 electrons in the L shell. So, it has 7 valence electrons. Fluorine is a highly electronegative element and attracts electrons to form a Fluorine ion (F⁻).

SF₆ is a covalently bonded compound. Covalent bonds are formed due to the sharing of electrons between two atoms. So in SF₆, six bonds are formed by the sulfur atom. It forms one bond with each of the six fluorine atoms. Each bond is comprised of two electrons.

Number of electrons surrounding sulfur = number of bonds formed by sulfur x Number of electrons in each bond

Number of electrons surrounding sulfur = 6 x 2

                                                                   = 12

Therefore, 12 electrons surround the sulfur atom in the SF₆ molecule.
