# Sulfur Valence Electrons (And How to Find them?)

So you have seen the above image by now, right?

Awesome! You can see that sulfur has 6 valence electrons.

But how can you say that Sulfur has 6 valence electrons
+
How can you find these valence electrons?

Let’s discuss this in short.

Sulfur has 6 valence electrons because there are 6 electrons present in the outermost shell of the Sulfur (S) atom.

Now let’s see how you can easily find the valence electrons of Sulfur atom (S).

If you don’t want to read the texts, then you can also watch this video.

## How to find the Valence Electrons? (2 Methods)

In order to find the valence electrons of Sulfur atom (S), you can use two methods.

### Method 1: From the Periodic Table

To find out the valence electrons of Sulfur, you have to see the position of sulfur in the periodic table.

More specifically, you have to see the group wise position of Sulfur element in the periodic table.

From the above image, you can see that the Sulfur (S) is present in the group 16 of periodic table.
(Note: Group 16 is also called group 6A).

So, as the sulfur element is present in group 16, it has 6 valence electrons.

In this way, by knowing the position of sulfur element in periodic table, you can easily find its valence electrons.

Now let’s see another method for finding the number of valence electrons in sulfur.

### Method 2: From the Electron Configuration

If you want to find the valence electrons of sulfur from its electron configuration, then you should know its electron configuration first.

Now there are many methods to write the electron configurations, but here I will show you the easiest method, i.e by using Aufbau principle.

Aufbau principle: The Aufbau principle simply states that the orbitals with the lower energy are filled first and then the orbitals with higher energy levels are filled.

According to the Aufbau principle, the orbitals are filled in the following order:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, and so on.

Also the maximum number of electrons that can be accommodated in s, p, d & f orbitals are mentioned in the below table.

Now let’s try to find the electron configuration of Sulfur by using the Aufbau principle.

Electron Configuration of Sulfur:

Follow the steps mentioned below to get the electron configuration of Sulfur.

• To write the electron configuration of sulfur, we should first know the total number of electrons present in a sulfur atom.
• The sulfur atom has a total of 16 electrons because its atomic number is 16 and it is a neutral atom. [2]
• Now we have to fill these 16 electrons in the atomic orbitals according to the Aufbau principle.
• According to the Aufbau principle, the electrons will be filled first in 1s orbital, then in 2s orbital, then in 2p orbital, and so on…
• So from the Aufbau principle, we can get the electron configuration of the sulfur atom as 1s2 2s2 2p6 3s2 3p4. [3]

Now in this electron configuration of sulfur, we have to see the total number of electrons present in the highest energy level.

You can see in the electron configuration of sulfur (1s2 2s2 2p6 3s2 3p4) that the highest energy level is 3. And the total number of electrons present in this energy level is 2 + 4 = 6.

So by knowing the electron configuration, we have found that the Sulfur has 6 valence electrons.

I hope you have understood the methods of finding the valence electrons in sulfur.
