Steps

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

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

Let’s break down each step in detail.

Find electrons

The atomic number of francium represents the total number of electrons of francium. Since the atomic number of francium is 87, the total electrons of francium are 87.

Write electron configuration

The electron configuration of francium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s1.

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

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 francium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s1. Hence, draw the blank orbital diagram of francium up to 7s subshell as follows:
