[Xe] 4f^14 5d^10

Explanation:

The atomic number of Au is 79.

Therefore, its configuration is:

1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 5s^2 5p^6 4f^14 5d^10 6s^1

or, [Xe] 4f^14 5d^10 6s^1

For Au^+, one electron is removed from the outermost 6s orbital, making the configuration,

[Xe] 4f^14 5d^10
