Electron configuration of Bismuth

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.
