Zinc Bohr model

The information on this page is ✔ fact-checked.

In the zinc Bohr model, a nucleus with 30 protons and 35 neutrons is at the core. Orbiting this nucleus are four electron shells, housing a total of 30 electrons.

To draw the zinc Bohr model, outline the 30 protons, 35 neutrons, and 30 electrons. Start by illustrating the nucleus, and then draw the four electron shells. The first three shells should contain 2, 8, and 18 electrons, respectively, while the fourth shell holds the remaining 2 electrons.

Steps

Write protons, neutrons, and electrons of zinc atom

Zinc has 30 protons, 35 neutrons, and 30 electrons.

Draw nucleus of zinc atom

The nucleus of a zinc atom contains 30 protons and 35 neutrons. So draw the nucleus of zinc 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 30 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 30 – 2 = 28 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 30 – 10 = 20 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, 3p, and 3d subshells. And the green, orange, and pink color represents the number of electrons in that subshell. This means that the 3^rd electron shell has a total of 18 electrons.

Now we have already used 28 electrons in 1^st, 2^nd, and 3^rd electron shells, so we have 30 – 28 = 2 electrons left. So in the next step, we have to draw the 4^th electron shell.

Draw 4^th electron shell

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

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

That’s it! This is the final Bohr model of zinc atom as we have used all 30 electrons: 2 electrons in the 1^st electron shell, 8 electrons in the 2^nd electron shell, 18 electrons in the 3^rd electron shell, and 2 electrons in the 4^th electron shell.
