Probably its atomic number (proton number), because this is how they are arranged already.
Other factors are their form (metal/non-metal) etc., which determines how they react with each other and bond.
Another important factor is the number of electrons in their valent (outer) shell. This is because it tells use how the atom will react/bond with other atoms, how 'violent' that reaction will be, and whether it will bond at all (eg. nobel gases)

Answer:
the only remote information i could find about this element was sodium
dicyanidoaurate(I)
sodium dicyanoaurate(1-)
Na[Au(CN)2]
sodium dicyanidoaurate(1-)
but as you see these go towards Na[Au(CN)2] not Na[Au(CN)4], so I will leave the rest up to you.
Have a good day.

this one tells you the element names.
