Aluminum Bohr model

The information on this page is ✔ fact-checked.

The aluminum Bohr model includes a nucleus with 13 protons and 14 neutrons. Surrounding this nucleus are three electron shells, carrying a total of 13 electrons.

To draw the aluminum Bohr model, outline the 13 protons, 14 neutrons, and 13 electrons. Start by illustrating the nucleus, and then draw the three electron shells. The first two shells should contain 2 and 8 electrons, respectively, while the third shell holds the remaining 3 electrons.

Steps

Write protons, neutrons, and electrons of aluminum atom

Aluminum has 13 protons, 14 neutrons, and 13 electrons.

Draw nucleus of aluminum atom

The nucleus of an aluminum atom contains 13 protons and 14 neutrons. So draw the nucleus of aluminum atom as follows:

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

Draw 1^st electron shell

Remember that we have a total of 13 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 13 – 2 = 11 electrons left. So in the next step, we have to draw the 2^nd electron shell.

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 13 – 10 = 3 electrons left. So in the next step, we have to draw the 3^rd electron shell.

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 3 electrons.

That’s it! This is the final Bohr model of aluminum atom as we have used all 13 electrons: 2 electrons in the 1^st electron shell, 8 electrons in the 2^nd electron shell, and 3 electrons in the 3^rd electron shell.
