SF6 Lewis Structure and Valence Electrons

Dr. B explains how to draw the Lewis structure for SF6. Starting with the calculation of total valence electrons, he places Sulfur at the center and surrounds it with six Fluorine atoms. He then draws bonds and ensures each Fluorine has a complete octet. Since Sulfur is in period 3, it can hold more than 8 electrons. Finally, he checks the formal charges, confirming they are zero, and concludes the structure is correct.

How many total valence electrons are present in the SF6 molecule?

• 60

• 48

How many valence electrons are used to form bonds between Sulfur and Fluorine in SF6?

• 18

• 24

• 12

• 6

Why can Sulfur hold more than 8 valence electrons in SF6?

• Because it is a noble gas

• Because it is highly electronegative

• Because it is in period 3

• Because it is a metal
