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

Explanation:

Step1: Determine valence electrons

Sulfur (S) has 6 valence electrons and each chlorine (Cl) has 7 valence electrons. So total valence electrons = 6 + 2×7 = 20.

Step2: Identify central atom

Sulfur is the central atom as it is less electronegative than chlorine.

Step3: Connect atoms with single - bonds

Connect S to each Cl with a single bond (a pair of electrons). This uses 4 electrons, leaving 20 - 4=16 electrons.

Step4: Distribute remaining electrons

Place the remaining 16 electrons as lone - pairs. Each Cl gets 3 lone - pairs and S gets 2 lone - pairs.

Answer:

The Lewis structure has a sulfur atom in the center with two single bonds to two chlorine atoms. Each chlorine atom has 3 lone - pairs of electrons and the sulfur atom has 2 lone - pairs of electrons.
