Silicon Bohr Model

The bohr model of silicon contains a nucleus having 14 protons and 14 neutrons in the center, and around this nucleus, there are three electron shells containing 14 electrons.

Steps

Here’s how you can draw the bohr model of silicon step by step.

Step #1: write protons, neutrons, and electrons of silicon atom
Step #2: draw nucleus of silicon atom
Step #3: draw 1^st electron shell
Step #4: draw 2^nd electron shell
Step #5: draw 3^rd electron shell

Let’s break down each step in detail.

#1 Write Protons, Neutrons, and Electrons of Silicon Atom

Silicon has 14 protons, 14 neutrons, and 14 electrons.

#2 Draw Nucleus of Silicon Atom

The nucleus of a silicon atom contains 14 protons and 14 neutrons. So draw the nucleus of silicon atom as follows:

Now in the next step, draw the 1^st electron shell and start marking electrons.

#3 Draw 1^st Electron Shell

Remember that we have a total of 14 electrons.

The 1^st electron shell (containing s subshell) can hold up to a maximum of 2 electrons. So draw the 1^st electron shell as follows:

In the above image, 1 represents the 1^st electron shell that contains 1s subshell. And the green color represents the number of electrons in that subshell. This means that the 1^st electron shell has a total of 2 electrons.

Since we have already used 2 electrons in the 1^st electron shell, now we have 14 – 2 = 12 electrons left. So in the next step, we have to draw the 2^nd electron shell.

#4 Draw 2^nd Electron Shell

The 2^nd electron shell (containing s subshell and p subshell) can hold up to a maximum of 8 electrons. So draw the 2^nd electron shell as follows:

In the above image, 2 represents the 2^nd electron shell that contains 2s and 2p subshells. And the green and orange color represents the number of electrons in that subshell. This means that the 2^nd electron shell has a total of 8 electrons.

Now we have already used 10 electrons in 1^st and 2^nd electron shells, so we have 14 – 10 = 4 electrons left. So in the next step, we have to draw the 3^rd electron shell.

#5 Draw 3^rd Electron Shell

The 3^rd electron shell (containing s subshell, p subshell, and d subshell) can hold up to a maximum of 18 electrons. So draw the 3^rd electron shell as follows:

In the above image, 3 represents the 3^rd electron shell that contains 3s and 3p subshells. And the green and orange color represents the number of electrons in that subshell. This means that the 3^rd electron shell has a total of 4 electrons.

That’s it! This is the final bohr model of silicon atom as we have used all 14 electrons: 2 electrons in the 1^st electron shell, 8 electrons in the 2^nd electron shell, and 4 electrons in the 3^rd electron shell.
