With the molecular formula Au2Cl6, the name gold trichloride is a simplification, referring to the empirical formula, AuCl3. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is common for gold compounds
the gold metal
Most common oxidation state of Gold is 0, because its most common form is its elementary form.
Gold can not rust. Rust is oxidation, and gold is inert to oxygen and even most acids.
By reduction-oxidation reaction you can extract metals, including Gold, from ore.
Although gold is unreactive, it forms many compounds with a range of oxidation states.
