Steps

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

Step #1: find electrons of neodymium
Step #2: write electron configuration of neodymium
Step #3: draw orbital diagram of neodymium

Let’s break down each step in detail.

#1 Find Electrons of Neodymium

The atomic number of neodymium represents the total number of electrons of neodymium. Since the atomic number of neodymium is 60, the total electrons of neodymium are 60.

#2 Write Electron Configuration of Neodymium

The electron configuration of neodymium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f4.

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

#3 Draw Orbital Diagram of Neodymium

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 neodymium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f4. Hence, draw the blank orbital diagram of neodymium up to 4f subshell as follows:
