# Lithium Bohr model

The information on this page is ✔ fact-checked.

In the lithium Bohr model, the nucleus is at the core with 3 protons and 4 neutrons. Revolving around the nucleus are two electron shells, carrying a total of 3 electrons.

To draw the lithium Bohr model, outline the 3 protons, 4 neutrons, and 3 electrons. Begin by illustrating the nucleus, and then depict the two electron shells. The first shell should accommodate 2 electrons, while the second holds 1 electron.

## Steps

### Write protons, neutrons, and electrons of lithium atom

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

### 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.

### 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.

### 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.
