Gold has an atomic number 79.
This means that the number of protons in gold is 79.
Since the number of electrons is equal to the number of protons, this means that gold has 79 electrons.
The electronic configuration of gold can be illustrated as follows:
[Xe] 4f14 5d10 6s1
From the above configuration, we can deduce that:
6 shells are occupied by electrons in gold
