## Steps

Here’s how you can draw the orbital diagram of fluorine step by step.

#1 Find electrons of fluorine
#2 Write electron configuration of fluorine
#3 Draw orbital diagram of fluorine

Let’s break down each step in detail.

### Find electrons

The atomic number of fluorine represents the total number of electrons of fluorine. Since the atomic number of fluorine is 9, the total electrons of fluorine are 9.

### Write electron configuration

The electron configuration of fluorine is 1s2 2s2 2p5.

Now in the next step, start drawing the orbital diagram for fluorine.

### Draw orbital diagram

Before drawing the orbital diagram, you should know the three general rules.

• Aufbau principle – electrons are first filled in lowest energy orbital and then in higher energy orbital
• Pauli exclusion principle – two electrons with the same spin can not occupy the same orbital
• Hund’s rule – each orbital should be first filled with one electron before being paired with a second electron

Also, you should know the number of orbitals in each subshell.

We can calculate the number of orbitals in each subshell using the formula: 2ℓ + 1

Where, ℓ = azimuthal quantum number of the subshell

For s subshell, ℓ = 0
For p subshell, ℓ = 1
For d subshell, ℓ = 2
For f subshell, ℓ = 3

So each s subshell has one orbital, each p subshell has three orbitals, each d subshell has five orbitals, and each f subshell has seven orbitals.

Now start to draw!

As mentioned above, the electron configuration of fluorine is 1s2 2s2 2p5. Hence, draw the blank orbital diagram of fluorine up to 2p subshell as follows:

In the above orbital diagram, the box represents an orbital. Each orbital has a capacity of two electrons. And the arrows (↑↓) are drawn inside the box to represent electrons.

Now 1s2 indicates that the 1s subshell has 2 electrons. So draw two arrows in the 1s box showing two electrons as follows:

2s2 indicates that the 2s subshell has 2 electrons. So draw two arrows in the 2s box showing two electrons as follows:

2p5 indicates that the 2p subshell has 5 electrons. So draw five arrows in the 2p box showing five electrons as follows:

That’s it! This is the final orbital diagram of fluorine as we have used all 9 electrons.
