Electron configuration of Bismuth

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

Bismuth has 83 electrons, and its electron configuration can be described as follows:

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p3.

Explanation

first shell

  • The first shell (principal quantum number n = 1) can hold a maximum of 2 electrons, so it is filled with 1s2.

second shell

  • The second shell (n = 2) can also hold a maximum of 2 electrons, so it is filled with 2s2 and 2p6.

third shell

  • The third shell (n = 3) is filled with 3s2 and 3p6, adjusting  a total of 8 electrons.

fourth shell

  • The fourth shell (n = 4) includes 4s2 and 3d10, adjusting  a total of 10 electrons.

fifth shell

  • The fifth shell (n = 5) contains 5s2, 4d10, and 5p6, adjusting  a total of 18 electrons.

sixth shell

  • The sixth shell (n = 6) includes 6s2, 4f14, 5d10, and 6p3, adjusting  a total of 32 electrons.
