# Lithium Bohr Model

The bohr model of lithium contains a nucleus having 3 protons and 4 neutrons in the center, and around this nucleus, there are two electron shells containing 3 electrons.

## Steps

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

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

Lithium has 3 protons, 4 neutrons, and 3 electrons.

### #2 Draw Nucleus of Lithium Atom

The nucleus of a lithium atom contains 3 protons and 4 neutrons. So draw the nucleus of lithium 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 3 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 3 – 2 = 1 electron 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 1 electron.

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