The bohr model of beryllium contains a nucleus having 4 protons and 5 neutrons in the center, and around this nucleus, there are two electron shells containing 4 electrons.
Steps
Here’s how you can draw the bohr model of beryllium step by step.
Step #1: write protons, neutrons, and electrons of beryllium atom
Step #2: draw nucleus of beryllium atom
Step #3: draw 1st electron shell
Step #4: draw 2nd electron shell
Let’s break down each step in detail.
#1 Write Protons, Neutrons, and Electrons of Beryllium Atom
Beryllium has 4 protons, 5 neutrons, and 4 electrons.

#2 Draw Nucleus of Beryllium Atom
The nucleus of a beryllium atom contains 4 protons and 5 neutrons. So draw the nucleus of beryllium atom as follows:

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 4 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:

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 4 – 2 = 2 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:

In the above image, 2 represents the 2nd electron shell that contains 2s subshell. And the green color represents the number of electrons in that subshell. This means that the 2nd electron shell has a total of 4 electrons.
That’s it! This is the final bohr model of beryllium atom as we have used all 4 electrons: 2 electrons in the 1st electron shell and 2 electrons in the 2nd electron shell.
