Verified step by step guidance1
Identify the atomic number of gold, which is 79. This means gold has 79 electrons.
Use the periodic table to determine the electron configuration order. Gold is in the 6th period and is a transition metal.
Start with the nearest noble gas configuration before gold, which is xenon ([Xe]), accounting for 54 electrons.
Continue filling the electron orbitals following the order: 6s, 4f, 5d. The 6s orbital is filled first with 2 electrons.
Fill the 4f orbital with 14 electrons, then the 5d orbital with 9 electrons to complete the configuration for gold.
