Silicon Bohr Model

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 1st electron shell
Step #4: draw 2nd electron shell
Step #5: draw 3rd 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:

Silicon Nucleus

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

#3 Draw 1st Electron Shell

Remember that we have a total of 14 electrons.

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

Silicon Shell 1

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

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

#4 Draw 2nd Electron Shell

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

Silicon Shell 2

In the above image, 2 represents the 2nd 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 2nd electron shell has a total of 8 electrons.

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

#5 Draw 3rd Electron Shell

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

Silicon Shell 3

In the above image, 3 represents the 3rd 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 3rd 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 1st electron shell, 8 electrons in the 2nd electron shell, and 4 electrons in the 3rd electron shell.
