In the hydrogen Bohr model, a nucleus with 1 proton and 0 neutrons resides at the center. Surrounding this nucleus is a single electron shell, housing 1 electron.[1]

To draw the hydrogen Bohr model, begin by noting the 1 proton and 0 neutrons. Create the nucleus, and then proceed to sketch the first electron shell.


Write protons, neutrons, and electrons of hydrogen atom

Hydrogen has 1 proton, 0 neutron, and 1 electron.

Draw nucleus of hydrogen atom

The nucleus of a hydrogen atom contains 1 proton and 0 neutron. So draw the nucleus of hydrogen 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 1 electron.

The 1st electron shell (containing s subshell) can hold up to a maximum of 2 electrons. So draw the 1st electron shell as follows:

Hydrogen shell 1

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 1 electron.

That’s it! This is the final Bohr model of hydrogen atom as we have only 1 electron and that is marked in the 1st electron shell.
