Manganese Bohr model

The Bohr model of manganese contains a nucleus having 25 protons and 30 neutrons in the center, and around this nucleus, there are four electron shells containing 25 electrons.

Steps

Here’s how you can draw the Bohr model of manganese step by step.

#1 Write protons, neutrons, and electrons of manganese atom
#2 Draw nucleus of manganese atom
#3 Draw 1st electron shell
#4 Draw 2nd electron shell
#5 Draw 3rd electron shell
#6 Draw 4th electron shell

Let’s break down each step in detail.

#1 Write protons, neutrons, and electrons of manganese atom

Manganese has 25 protons, 30 neutrons, and 25 electrons.

#2 Draw nucleus of manganese atom

The nucleus of a manganese atom contains 25 protons and 30 neutrons. So draw the nucleus of manganese atom as follows:

Manganese nucleus
Manganese 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 25 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:

Manganese shell 1
Manganese 1st electron shell drawn

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 25 – 2 = 23 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:

Manganese shell 2
Manganese 2nd electron shell drawn

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 25 – 10 = 15 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:

Manganese shell 3
Manganese 3rd electron shell drawn

In the above image, 3 represents the 3rd electron shell that contains 3s, 3p, and 3d subshells. And the green, orange, and pink color represents the number of electrons in that subshell. This means that the 3rd electron shell has a total of 13 electrons.

In the 3rd electron shell, the 3d subshell has only five electrons. This is because according to the aufbau principle, the 4s subshell is filled first and then 3d, 4p, 5s… and so on.

Now we have already used 23 electrons in 1st, 2nd, and 3rd electron shells, so we have 25 – 23 = 2 electrons left. So in the next step, we have to draw the 4th electron shell.

#6 Draw 4th electron shell

The 4th electron shell (containing s subshell, p subshell, d subshell, and f subshell) can hold up to a maximum of 32 electrons. So draw the 4th electron shell as follows:

Manganese shell 4
Manganese 4th electron shell drawn

In the above image, 4 represents the 4th electron shell that contains 4s subshell. And the green color represents the number of electrons in that subshell. This means that the 4th electron shell has a total of 2 electrons.

That’s it! This is the final Bohr model of manganese atom as we have used all 25 electrons: 2 electrons in the 1st electron shell, 8 electrons in the 2nd electron shell, 13 electrons in the 3rd electron shell, and 2 electrons in the 4th electron shell.
