Chlorine orbital diagram

The information on this page is ✔ fact-checked.

In the chlorine orbital diagram, the 1s subshell accommodates two electrons, the 2s subshell holds another pair, and the 2p subshell encompasses six electrons. Shifting to the 3s subshell, it contains two electrons, and the 3p subshell holds five electrons, totaling seventeen electrons.

To illustrate the chlorine orbital diagram, begin by determining the number of electrons from the periodic table. Take note of the electron configuration for reference and follow the three fundamental rules: the Aufbau principle, Pauli exclusion principle, and Hund’s rule. This systematic approach ensures an accurate representation of chlorine’s orbital arrangement.

Steps

Find electrons

To find out how many electrons chlorine has, check its atomic number on the periodic table. Chlorine, with an atomic number of 17, contains seventeen electrons.

Write electron configuration

The electron configuration of chlorine is 1s² 2s² 2p⁶ 3s² 3p⁵.

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

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 chlorine is 1s² 2s² 2p⁶ 3s² 3p⁵. Hence, draw the blank orbital diagram of chlorine up to 3p 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:

2p⁶ indicates that the 2p subshell has 6 electrons. So draw six arrows in the 2p box showing six electrons as follows:

3s² indicates that the 3s subshell has 2 electrons. So draw two arrows in the 3s box showing two electrons as follows:

3p⁵ indicates that the 3p subshell has 5 electrons. So draw five arrows in the 3p box showing five electrons as follows:

That’s it! This is the final orbital diagram of chlorine as we have used all 17 electrons.
