Why is gold found in the metallic form?
Gold is characterised chemically by an extreme indifference to the action of all bodies usually met with in nature. Its simpler compounds are formed with difficulty, and decompose readily, especially when heated. The result is that gold is found in nature chiefly in the metallic form, and the mineralogist has, therefore, few compounds to consider.
What kind of reaction does gold have with water?
Gold does not react with water. Gold metal reacts with chlorine, Cl 2, or bromine, Br 2, to form the trihalides gold (III) chloride, AuCl 3, or gold (III) bromide, AuBr 3, respectively. On the other hand, gold metal reacts with iodine, I 2, to form the monohalide gold (I) chloride, AuI.
Which is the correct formula for the compound gold?
The gold in them is not present as an elementary ion, but forms part of complex ions.
