【】How Many Valence Electrons Does Silicon(Si) Have?

Silicon has four valence electrons.

Explanation:

Now I am going to show you how many  valence electrons  silicon have in just 5 steps.

             Step-1:

First, find the atomic number of silicon from periodic table.

From periodic table ,we see that the atomic number of silicon is 14.

                 Step-2:

We know that the atomic number of silicon is 14.So silicon has 14 protons and 14 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1.

                Step-3:

Now write the electron configuration of silicon .

Si(14)=1s²2s²2p⁶3s²3p²

                Step-4:

Si(14)=1s²2s²2p⁶3s²3p²

Now we will find out valence shell of silicon from the electronic configuration of  silicon.

Si(14)=1s²2s²2p⁶3s²3p²

Valence shell can be found from the highest number of principal quantum number.

You know that principal quantum number is expressed by n.

Si(14)=1s²2s²2p⁶3s²3p²

Here the highest value of n is 3.SoThe valence shell of silicon is 3s²3p²

                 Step-5

In this step,we will find out the valence electrons of silicon.

We have to know that the electrons of valence shell are called valence electrons.

Si(14)=1s²2s²2p⁶3s²3p²

From the above electron 

configuration 

of silicon,we see 

that silicon has 4 

valence electrons in its 

valence shell(3s²3p²).

So there are four valence electrons of silicon.
