# Helium Bohr Model

The bohr model of helium contains a nucleus having 2 protons and 2 neutrons in the center, and around this nucleus, there is one electron shell containing 2 electrons.

## Steps

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

Step #1: write protons, neutrons, and electrons of helium atom
Step #2: draw nucleus of helium atom
Step #3: draw 1st electron shell

Let’s break down each step in detail.

### #1 Write Protons, Neutrons, and Electrons of Helium Atom

Helium has 2 protons, 2 neutrons, and 2 electrons.

Learn how to find: Helium Protons Neutrons Electrons

### #2 Draw Nucleus of Helium Atom

The nucleus of a helium atom contains 2 protons and 2 neutrons. So draw the nucleus of helium 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 2 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.

That’s it! This is the final bohr model of helium atom as we have only 2 electrons and that are marked in the 1st electron shell.
