# Boron Bohr Model

The bohr model of boron contains a nucleus having 5 protons and 6 neutrons in the center, and around this nucleus, there are two electron shells containing 5 electrons.

## Steps

Here’s how you can draw the bohr model of boron step by step.

Step #1: write protons, neutrons, and electrons of boron atom
Step #2: draw nucleus of boron 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 Boron Atom

Boron has 5 protons, 6 neutrons, and 5 electrons.

### #2 Draw Nucleus of Boron Atom

The nucleus of a boron atom contains 5 protons and 5 neutrons. So draw the nucleus of boron 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 5 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 5 – 2 = 3 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 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 3 electrons.

That’s it! This is the final bohr model of boron atom as we have used all 5 electrons: 2 electrons in the 1st electron shell and 3 electrons in the 2nd electron shell.
