Scandium Bohr model
Scandium Bohr model

In the scandium Bohr model, the nucleus is composed of 21 protons and 24 neutrons. Surrounding this nucleus are four electron shells, accommodating a total of 21 electrons.

To draw the scandium Bohr model, outline the 21 protons, 24 neutrons, and 21 electrons. Start by illustrating the nucleus, and then draw the four electron shells. The first three shells should contain 2, 8, and 9 electrons, respectively, while the fourth shell holds the remaining 2 electrons.

Steps

Write protons, neutrons, and electrons of scandium atom

Scandium has 21 protons, 24 neutrons, and 21 electrons.

Draw nucleus of scandium atom

The nucleus of a scandium atom contains 21 protons and 24 neutrons. So draw the nucleus of scandium atom as follows:

Scandium nucleus

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

Draw 1st electron shell

Remember that we have a total of 21 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:

Scandium 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 21 – 2 = 19 electrons left. So in the next step, we have to draw the 2nd electron shell.

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:

Scandium shell 2
Scandium 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 21 – 10 = 11 electrons left. So in the next step, we have to draw the 3rd electron shell.

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:

Scandium shell 3
Scandium 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 9 electrons.

In the 3rd electron shell, the 3d subshell has only one electron. 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 19 electrons in 1st, 2nd, and 3rd electron shells, so we have 21 – 19 = 2 electrons left. So in the next step, we have to draw the 4th electron shell.

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:

Scandium shell 4
Scandium 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 scandium atom as we have used all 21 electrons: 2 electrons in the 1st electron shell, 8 electrons in the 2nd electron shell, 9 electrons in the 3rd electron shell, and 2 electrons in the 4th electron shell.
