It is gold zero. Relativistic effects stabilizes the 6s orbital to the extent that it accepts a second electron from the other gold atom.
Check for example J. Chem. Ed. 1991, 68, 110 for a more thorough explanation.
The chemical formula for gold carbonate is Au2(CO3)2.
The formula for gold(III) chromate is Au2(CrO4)3.
The simplest Gold Sulfate compound is Gold (II) Sulfate AuSO4, ionic formula Au2+ SO42-. There also exists a very unstable Gold (III) Sulfate Au2(SO4)3, ionic formula Au3+2 (SO4)2-3. Additionally, gold forms a number of quite complex sulfate structures such as (a) the Gold (III) Sulfate ion[Au(S04)2]1-, ionic formula [Au3+ (SO4)2-2]1- (b) the Auryl Sulfate compound AuOHSO4, ionic formula Au3+ (OH)1- (SO4)2- (c) the infinite sheet stack described by the formula [(Au2)(SO4)4/2], ionic formula [(Au4+2) (SO4)2-4/2].

gold + sulphuric acid = gold sulphate + hydrogen :)
Gold (III) Sulfate is an extremely unstable compound with the molecular formula Au2(SO4)3 and ionic formula Au3+2 (SO4)2-3.
The chemical formula for gold(I) carbonate is Au2(CO3)3. It is a compound formed by gold in its +1 oxidation state combined with carbonate ions.
The formula for gold(III) sulfate is Au2(SO4)3.
The formula for gold(II) sulfate is Au2(SO4)3.
The chemical formula for gold(I) sulfite is Au2(SO3)3.
The chemical compound gold(III) dichromate has the formula Au2(Cr2O7)3. It is a salt containing gold in the +3 oxidation state and dichromate ions. This compound is highly unstable and not commonly encountered in practical applications.
Presumably you mean gold sulphate? Gold sulphate does not exist except as part of a complex salt.
