Electron configuration of gold

The electron configuration of gold is:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ 7s².

Explanation

Atomic number of gold: 79

A brief description of its electronic configuration is as follows;

Two electrons in the first shell’s 1s orbital.

2 electrons are present in shell 2

2 electrons in the 3s orbital

and 6 in the 3p orbitals,2 in each of the 3px, 3py, and 3pz contribute in make up of shell 3.

2 electrons in the 4s orbital
and 10 in the 3d orbitals—2 in each of the 3dxy, 3dxz, 3dyz, 3dx²-y², and 3dz—make up shell 4.

10 electrons in the 4d orbitals—

With regard to the electrons in shell 6,

there are two in the 6s orbital,
fourteen in the 4f orbitals (two in each of the 4f),
and ten in the 5d orbitals (two in each of the 5dxy, 5dxz, 5dyz, 5dx²-y², and 5dz).

2 electrons in the 7s orbital for shell 7.
