Sulfur Lewis Dot Structure: Drawing, Several Compounds And Detailed Explanations

Lewis dot structure gives information about outermost shell electrons of an atom. This article is discussing about the Sulfur lewis dot structure involving in bonding with different elements.

Sulfur lewis dot structure is written by Atomic symbol of that atom. The electrons written as dots may be bonding or unshared electrons. Sulfur is a ‘group 16’ element with six outer most shell electrons. Sulfur always tends to get two electrons from donor atom. This gives it stable electronic configuration.

Sulfur atom lewis dot structure

Sulfur is a ‘Group 16’ element in Periodic table. From the Lewis dot structure, we can predict different properties of Sulfur.

Sulfur has sixteen electrons in electronic orbital. Electronic configuration of Sulfur: 1s2 2s2 2p6 3s2 3p4.

To draw the electron dot structure of Sulfur atom write the atomic symbol of Sulfur that is “S”. After this we have to count the outer most shell electrons. For Sulfur there are six valence electrons in 3s and 3p shell. These electrons are shown by dots around the atomic symbol.

Sulfur ion lewis dot structure

Sulfur is a ‘Group 16’ element. It has six electrons in outer most shell 3s and 3p.

From Octet rule we know that every element covers its outer most shell with eight electrons. This makes the element more stable. So Sulfur needs two more electrons for the stability like nearest Noble gas. Thus it becomes a negative ion.

The symbol of Sulfur (S) is written and around it all the outer most shell electrons are shown by dot sign. This whole should be written inside a bracket. The negative charge gained by the atom for accepting electrons must be written right outside of the bracket.

Sulfuric acid lewis dot structure

Sulfuric acid is a well known chemical for various uses. Lewis dot structure gives us information about the valence electrons of atoms forming the molecule.

Sulfuric acid forms with one Sulfur, four Oxygen and two Hydrogen atoms. Electronic configuration of Sulfur: [Ne] 3s2 3p4. Electronic configuration of Oxygen: 1s2 2s2 2p4. Electronic configuration of Hydrogen: 1s1. So total thirty-two outer most shell electrons are participating in molecule formation.

Sulfuric acid has two S-O sigma bonds, two S=O pi bonds and two O-H sigma bonds. Sixteen electrons are involved in the bonds. Remaining Sixteen electrons stay as non bonding electrons. 

Electropositive atom Sulfur is central atom. It has no non bonding electrons. Each of four Oxygen atoms contain two unpaired electron pairs . So there are sixteen lone pairs in the molecule which do not participate in bonding.

Sulfur monoxide lewis dot structure

Oxygen and Sulfur both are ‘group 16’ element in Periodic table. So they have six outer most shell electrons.

In order to get octet fill up stable electronic configuration they both need two electrons. The two atoms share their electrons and are stable like nearest Noble gas.

Sulfur and Oxygen share four (two pairs) electrons and form a double bond. This is written as double straight line (=). Beside that each of the atoms contains two pair of non bonding electrons.

Fluorine is a ‘group 17’ element in periodic table. It has seven outer most shell electrons in 2s and 2p shell. Electronic configuration of Sulfur (valence shell): [Ne] 3s2 3p4.

Fluorine atom needs one electron to make stable electronic configuration. Sulfur shares its four outer most shell electrons to four electronegative Fluorine atoms.

The bonding electron pairs between Sulfur and Fluorine are written as straight lines. Sulfur has two unshared electrons.

Aluminum and Sulfur lewis dot structure

 Aluminum is a ‘group 13’ element with outer most shell electronic configuration: [Ne] 3s2 3p1. Six electrons are in 3s and 3p shell of Sulfur.

According to Octet rule Aluminum atom transfers these three outer most shell electrons. These electrons are accepted by Sulfur atom. In this way both of them are able to form stable electronic configuration.

Aluminum atom produce positive ion where Sulfur atom become negative ion. These two oppositely charged ions form Al2S3 molecule.

Lithium and Sulfur lewis dot structure

Lithium is a ‘group 1’ element in periodic table with electronic configuration: 1s2 2s1.

To get stable electronic configuration, Lithium atom donate the outer most shell electron of 2s shell. Become a positive ion. This electron is accepted by Sulfur atom and produce Sulfide ion.

So two Lithium ions make bond with one Sulfide ion. This results in formation of Li2S

Sodium and Sulfur lewis dot structure

Sodium is a ‘group 1’ element in periodic table with electronic configuration: 1s2 2s2 2p6 3s1. So it has one outer most shell electron.

Sodium atom transfers that 3s shell electron to get stable octet structure. That electron accepted by Sulfur vacant shell. So two Sodium ions coordinate with one Sulfide ion. This results in Na2S molecule formation.

Central atom Sulfur has two pairs of non bonding electrons. The electrons which participated in bonding are shown as straight lines. Sodium atoms have no non bonding electrons.

Potassium and Sulfur lewis dot structure

Potassium is a ‘group 1’ element in periodic table. It has one outer most shell electron in 4s electronic shell ([Ar] 4s1).

Potassium atom transfers this outer most shell electron to maintain Octet rule and become a positive ion. The electron is accepted by Sulfur atom and form Sulfide ion.

Sulfur atom needs two electrons to fill up its valence electronic shell; it combines with two Potassium ions and produce K2S.

Two sigma bonds between Potassium and Sulfur are represented as straight lines.

Calcium and Sulfur lewis dot structure

Calcium is a ‘group 2’ element in periodic table with 20 electrons in orbital. Its outer most shell electronic configuration:  [Ar] 4s2.

It transfers outer most shell electrons and forms a positive ion. This gives Calcium stable electronic structure like nearest Noble gas. Sulfur atom needs two electrons to get octet structure.

So Calcium atom donates electrons with sulfur atom and form CaS molecule.

Beryllium is a ‘group 2’ element in periodic table. Its electronic configuration: 1s2 2s2.

To achieve stability Beryllium donates two valence electrons. These are taken by Sulfur atom to form Sulfide ion. These two opposite ions attracted two each other and form BeS molecule

Magnesium is a ‘group 2’ element with outer most shell electronic configuration:  [Ne] 3s2.

To draw the structure, we count the total electrons of outer shell. Magnesium atom donates two 3s shell electrons and produced positive ion. These electrons are accepted by Sulfur atom and form negative ion.

These two opposite ions are attracted two each other and form MgS molecule. Magnesium ion does not have any nonbonding electron pair. Sulfide ion has three pairs of electrons which not participate in bonding.

Strontium is a ‘group 2’ element in periodic table with outer most shell electronic configuration [Kr] 5s2.

According to octet rule every atom wants octet fill up structure to be stable. To satisfy this, Strontium transfers its two 5s shell valence electrons which are taken by Sulfur atom and produce Sulfide ion.

Sulfur is a ‘group 16’ element (electronic configuration: [Ne] 3s2 3p4) and Oxygen is also a ‘group 16’ element (electronic configuration: 1s2 2s2 2p4) in Periodic table.

To draw the electron dot structure we count all the outer most shell electrons that participate in the molecule formation. Both Sulfur and Oxygen has two less electrons to satisfy the stable electronic configuration. So two Oxygen atoms shares electron with one Sulfur atom.

Less electronegative Sulfur is central atom here. It shares two electron pair with each of the Oxygen atom. So two pi bonds form, shown by the symbol (=) .

In the molecule Sulfur contains one unshared electron pair. There are two lone pairs of electron on each Oxygen atoms. These are written as dots.
