Phosphorus Bohr Model

Phosphorus Bohr Model

The bohr model of phosphorus contains a nucleus having 15 protons and 16 neutrons in the center, and around this nucleus, there are three electron shells containing 15 electrons.

Steps

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

Step #1: write protons, neutrons, and electrons of phosphorus atom
Step #2: draw nucleus of phosphorus atom
Step #3: draw 1st electron shell
Step #4: draw 2nd electron shell
Step #5: draw 3rd electron shell

Let’s break down each step in detail.

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

Phosphorus has 15 protons, 16 neutrons, and 15 electrons.

#2 Draw Nucleus of Phosphorus Atom

The nucleus of a phosphorus atom contains 15 protons and 16 neutrons. So draw the nucleus of phosphorus atom as follows:

Phosphorus Nucleus

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 15 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:

Phosphorus 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 2 electrons.

Since we have already used 2 electrons in the 1st electron shell, now we have 15 – 2 = 13 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:

Phosphorus Shell 2

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 8 electrons.

Now we have already used 10 electrons in 1st and 2nd electron shells, so we have 15 – 10 = 5 electrons left. So in the next step, we have to draw the 3rd electron shell.

#5 Draw 3rd Electron Shell

The 3rd electron shell (containing s subshell, p subshell, and d subshell) can hold up to a maximum of 18 electrons. So draw the 3rd electron shell as follows:

Phosphorus Shell 3

In the above image, 3 represents the 3rd electron shell that contains 3s and 3p subshells. And the green and orange color represents the number of electrons in that subshell. This means that the 3rd electron shell has a total of 5 electrons.

That’s it! This is the final bohr model of phosphorus atom as we have used all 15 electrons: 2 electrons in the 1st electron shell, 8 electrons in the 2nd electron shell, and 5 electrons in the 3rd electron shell.
