79 protons, 79 electrons and 118 neutrons

Explanation:

Hi, the atomic number of an element is equal to the number of protons it has.

For gold (Au):

If the atom is uncharged (and only if it is uncharged), the number of electrons it has is equal to the number of protons.

For gold (Au):

At last, the atomic mass represents the protons plus the neutrons an atom has in its core. So:

i'm pretty sure its b i might be wrong though!
