Question

on a sheet of paper, draw the lewis structure for the following compound. a link to the periodic table has been provided for you. sci₂
sample answer: :cl—s—cl:
check all features below that you included in your lewis structure.
correct number of s and cl atoms
s as the central atom
link (single bond) between s and each of the two cl atoms
six dots (electrons) associated with each cl atom
four dots (electrons) associated with the s atom
no other lines or dots

Explanation:

Step1: Determine central atom

Sulfur (S) is less electronegative than chlorine (Cl), so S is the central atom.

Step2: Calculate valence - electrons

S has 6 valence electrons and each Cl has 7 valence electrons. Total valence electrons = 6+(2×7)=20.

Step3: Form single - bonds

Form single bonds (S - Cl) between S and each Cl atom. 2 single bonds use 4 electrons.

Step4: Distribute remaining electrons

We have 20 - 4 = 16 electrons left. Place 6 electrons as 3 lone - pairs around each Cl atom and 4 electrons as 2 lone - pairs around the S atom.

Answer:

All of the features should be checked:

• correct number of S and Cl atoms
• S as the central atom
• single bond between S and each of the two Cl atoms
• six dots (electrons) associated with each Cl atom
• four dots (electrons) associated with the S atom
• no other lines or dots
