It melts at 115.21 °C (239.38 °F), boils at 444.6 °C (832.3 °F), and sublimes easily.

We will find an answer for “How Many Valence Electrons Does Sulfur Have” in this article together. We hope that you’ll know much more about valence electrons of sulfur after this article. Let’s see what is the sulfur valence electrons.

How many protons does sulfur have?

Protons of a certain atom like sulfur can be found easily. Atomic number of the sulfur atom is enough to find how many protons sulfur has. Atomic number of Sulfur is 16. Atomic mass of Sulfur is 32. Proton number is equal to atomic number in S atom.

Also, if you want to find neutron number in a certain atom, you can easily do it with the knowledge of atomic mass. Neutron can be found by substracting proton number from atomic mass. So, neutron number is equal to 32-16 = 16. And we know that electrons are equal to protons. So, Sulfur has 16 protons, 16 neutrons and 16 electrons. What an element, right!

Sulfur Valence Electrons

Sulfur is an element which is placed in group 16 of periodic table. How can we find valence electrons? We can find valence electrons by finding the electrons in the last orbit or the last shell of Sulfur atom. We’re looking for how many electrons are present in the last shell.

If an atom wants to create a bond with another atom, the valence electrons of both atoms gain importance. Valence electrons helps us to understand the atoms. Sulfur is the 16th element in the periodic table. It means that Sulfur atom has 16 protons and 16 electrons.

There is an easy path to find valence electron which are located in the last shell of Sulfur. The easy way is to write the electron configuration. The electrons in the last shell is equal to sulfur (S) valence electrons. So, Sulfur valence electrons are six.

How many valence electrons does s have

Sulfur has 16 protons in total because it has 16 electrons located in its orbitals. How to find how many valence electrons s has? To find out how many valence electrons s has, the first thing to do is writing the electron configuration of Sulfur. Because S valence electrons are present in the last shell of the electron configuration of sulfur. In conclusion, S has six valence electrons in total.

How many valence electrons are in an atom of sulfur

There is an easy way to determine how many valence electrons are in an atom of sulfur but you need to follow 3 steps to calculate it. We need the recipe, right? So, if you are looking for the valence electrons in a sulfur atom, what you need is electron configuration of sulfur! Easy.

Once you have the full electron configuration, you can easily calculate the valence electrons. Here in this topic, we’ll look for the electron configuration of sulfur in the first step and then we will use this information to go through the second and third steps.

Below image shows the summary of principal energy levels, sublevels and orbitals to write down the electron configuration. As you can see, a different number of electrons can be present in every sublevels.

Principal+Energy+Level+Number+of+Sublevels+Type+of+Sublevel
Summary of Principal Energy Levels, Sublevels, and Orbitals. Principal Energy Level. Number of Sublevels. Type of Sublevel. n= s (1 orbital) n= s (1 orbital), 2p (3 orbitals) n= s (1 orbital), 3p (3 orbitals) 3d (5 orbitals) n= s (1 orbital), 4p (3 orbitals) 4d (5 orbitals) 4f (7 orbitals)

Now we can write the electron configuration easily since we know Bohr model and sub-orbits.

First Step : Calculate the number of electrons in sulfur(S)

Let’s start! First step is calculating number of electrons of a sulfur atom, right? How can we find electrons in sulfur? If you said to yourself “check the periodic table”, congratz, that’s right. Because if we know the atomic number, we can find the proton number. And we can find the proton number, we can find the electron number. Very easy to remember, what do you say? Let’s check periodic table to find the atomic number of Sulfur atom. Here is the periodic table:

Atomic number of sulfur on periodic table

Periodic table can give us what we need because the atomic number of every element is indicated in the periodic table. The number above the elements are atomic numbers. We need the atomic number of sulfur so we need to find where is sulfur in the periodic table. Sulfur is a group 16 element. You can find it under Oxygen and above Se in the periodic table. The number above the Sulfur is 16. Which means that, atomic number of S atom is 16.

In conclusion, electron number is equal to atomic number for S atom. As we can see in the periodic table, Sulfur atomic number is 16 which means that the total number of electrons for Sulfur atom is 16.

Second Step : Write the electron configuration for sulfur

First step is done. Let’s move to the second step. We know the electron number of sulfur, now we need electron configuration. Electron configuration has a very important role for every atom because it shows us the valence electrons. Electron configuration indicates how to distribute electrons to sublevels.

In the first step, we found that sulfur atom has sixteen electrons. According to the Bohr model, we can arrange 16 electrons to write the electron configuration. First orbit which is 1s should have two electrons. The second orbit which is 2s and 2p should have eight electrons. The third orbit which is 3s and 3p should have six electrons. Sublevel distribution of electrons of sulfur is respectively 2, 8, 6. By using sub-orbits, we can write the electron configuration for sulfur as 1s2 2s2 2p6 3s2 3p4.

Third Step : Find the last shell and calculate valence electrons for sulfur atom

Here comes the last step.

In the second step, we were able to write the electron configuration of sulfur thanks to the information we got in the first step. In the third step which is the last, we need to find which shell is the valence shell for sulfur atom. Because last shell of the electron configuration is valence shell and the electrons in a valence shell is equal to valence electrons for every atom. According to the electron configuration of sulfur, the last shell is 3s2 3p4 and it has six electrons. In conclusion, the valence electrons in sulfur are 6.

What is the valency of sulfur(S)?

Valency is called to indicate the capability of forming bonds with other atoms. Valency number or with its other name valence is the number of unpaired electrons in the atom. How to find unpaired electrons? Unpaired electrons can be found in the last shell of atoms.

Electron configuration for S atom is 1s2 2s2 2p6 3s2 3p4. According to the electron configuration of sulfur, there are 2 unpaired electron in the last orbit which is 3p4. In conclusion, the valency of S atom is 2.

How many valence electrons does sulfur ion(S2-) have?

According to the electron configuration that we wrote before, there are 6 electrons in the last shell of S atom. And the valency of S atom is 2. If an atom has 4, 5 and 6 electrons in its last shell, it receives electrons to form a bond with another atom.

Anion is the name of the elements that wants to receive electrons to form a bond with another atom. Sulfur is an anion because Sulfur wants to receive electrons to form a bond.

S + 2e → S2-

Electron configuration for sulfur ion(S2-) or sulfide is 1s2 2s2 2p6 3s2 3p6 . As we know, the total number of electrons in the last shell equal to the valence electrons. The last shell of S ion has 8 electrons 3s2 3p6. According to the electron configuration of Sulfur ion, the valence electrons of sulfur ion are eight.
