Gold is a transition metal and sulfur is a nonmetal so the only bond here could be ionic.
An ionic compound is an example of a chemical compound.
A covalent compound, not ionic
Copper(II) sulfide is an ionic compound.
No, like all sodium (Na) compound it is ionic.
Is ionic
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].
Au2(Cr2O7)3
Gold (III) Sulfate is an extremely unstable compound with the molecular formula Au2(SO4)3 and ionic formula Au3+2 (SO4)2-3.
