Magnesium Bohr model

The information on this page is ✔ fact-checked.

In the magnesium Bohr model, the nucleus consists of 12 protons and 12 neutrons. Surrounding this nucleus are three electron shells, containing a total of 12 electrons.

To draw the magnesium Bohr model, represent the 12 protons, 12 neutrons, and 12 electrons. Commence by sketching the nucleus, and then illustrate the three electron shells. The first two shells should contain 2 and 8 electrons, respectively, while the third shell holds the remaining 2 electrons.

Steps

Write protons, neutrons, and electrons of magnesium atom

Magnesium has 12 protons, 12 neutrons, and 12 electrons.

Draw nucleus of magnesium atom

The nucleus of a magnesium atom contains 12 protons and 12 neutrons. So draw the nucleus of magnesium 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 12 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 12 – 2 = 10 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 12 – 10 = 2 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 subshell. And the green color represents the number of electrons in that subshell. This means that the 3^rd electron shell has a total of 2 electrons.

That’s it! This is the final Bohr model of magnesium atom as we have used all 12 electrons: 2 electrons in the 1^st electron shell, 8 electrons in the 2^nd electron shell, and 2 electrons in the 3^rd electron shell.
