By: Prof. Dr. Fazal Rehman Shamil | Last updated: February 3, 2024

The electron configuration of iridium (Ir) is:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d⁷

Explanation:

first shell

• This denotes the presence of two electrons in the 1s orbital in the first shell (n=1).

second shell

• There are 2 electrons in the 2s orbital
• and 6 electrons in the 2p orbital in the second shell (n=2).

third shell

• There are 2 electrons in the 3s orbital
• and 6 electrons in the 3p orbital in the third shell (n=3).

fourth shell

• There are 2 electrons in the 4s orbital
• and 10 electrons in the 3d orbital in the fourth shell (n=4).
• 4p orbital, also present which has six electrons.

fifth shell

• The fifth shell (n=5) has 2 electrons in the 5s orbital
• and 10 electrons in the 4d orbital.
• This configuration is designated as 5s² 4d¹⁰.
• There are 6 electrons in the 5p orbital in the fifth shell.

sixth shell

• There are two electrons in the 6s orbital in the sixth shell (n=6).

fourth shell again

• The 4f orbital in the fourth shell has 14 electrons.

fifth shell’s again

• The fifth shell’s 5d orbital has seven electrons.
