So, what is the atomic number of gold?

Explanation:

For gold, #Z=79#...and we gots 79 electrons to distribute.. Following the #"aufbau scheme"#, we build on the configuration of the last Noble gas, i.e. #Xe, Z=54#. Of course, we got a whole lanthanide series, cerium to lutetium, between xenon and goldo…

Let's try #Au:underbrace([Xe])_"54 electrons"4f^(14)5d^(10)6s^1#

Does the electornic charge balance the atomic number? If the answer is no, then my answer must be wrong....
