Carbon orbital diagram

The orbital diagram of carbon shows that the 1s subshell has 2 electrons, the 2s subshell has 2 electrons, and the 2p subshell has 2 electrons.

Steps

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

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

Let’s break down each step in detail.

Find electrons

The atomic number of carbon represents the total number of electrons of carbon. Since the atomic number of carbon is 6, the total electrons of carbon are 6.

Write electron configuration

The electron configuration of carbon is 1s2 2s2 2p2.

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

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 carbon is 1s2 2s2 2p2. Hence, draw the blank orbital diagram of carbon up to 2p subshell as follows:

Blank orbital diagram of carbon

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:

Two arrows drawn in 1s box represent 1s2

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

Two arrows drawn in 2s box represent 2s2

2p2 indicates that the 2p subshell has 2 electrons. So draw two arrows in the 2p box showing two electrons as follows:

Two arrows drawn in 2p box represent 2p2

That’s it! This is the final orbital diagram of carbon as we have used all 6 electrons.
