The orbital diagram of antimony shows that the 1s subshell has 2 electrons, the 2s subshell has 2 electrons, the 2p subshell has 6 electrons, the 3s subshell has 2 electrons, the 3p subshell has 6 electrons, the 4s subshell has 2 electrons, the 3d subshell has 10 electrons, the 4p subshell has 6 electrons, the 5s subshell has 2 electrons, the 4d subshell has 10 electrons, and the 5p subshell has 3 electrons.
Steps
Find electrons
The atomic number of antimony represents the total number of electrons of antimony. Since the atomic number of antimony is 51, the total electrons of antimony are 51.
Write electron configuration
The electron configuration of antimony is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p3.

Now in the next step, start drawing the orbital diagram for antimony.
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 antimony is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p3. Hence, draw the blank orbital diagram of antimony up to 5p 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:
3p6 indicates that the 3p subshell has 6 electrons. So draw six arrows in the 3p box showing six electrons as follows:
4s2 indicates that the 4s subshell has 2 electrons. So draw two arrows in the 4s box showing two electrons as follows:
3d10 indicates that the 3d subshell has 10 electrons. So draw ten arrows in the 3d box showing ten electrons as follows:
4p6 indicates that the 4p subshell has 6 electrons. So draw six arrows in the 4p box showing six electrons as follows:
5s2 indicates that the 5s subshell has 2 electrons. So draw two arrows in the 5s box showing two electrons as follows:
4d10 indicates that the 4d subshell has 10 electrons. So draw ten arrows in the 4d box showing ten electrons as follows:
5p3 indicates that the 5p subshell has 3 electrons. So draw three arrows in the 5p box showing three electrons as follows:
That’s it! This is the final orbital diagram of antimony as we have used all 51 electrons.
