One chemical property of gold is its resistance to oxidation and corrosion. Another important property is its ability to form compounds with other elements, such as copper or silver, to create alloys. Additionally, gold is known for its high malleability and ductility, making it easy to shape into various forms.
Gold jewelry being unaffected by perspiration is a chemical property. Chemical properties describe how a substance interacts with other substances to form new substances. In this case, the lack of reaction between gold and perspiration is a chemical property related to the metal's inertness or non-reactivity.

physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
It's a physical property. Consider the metal gold. It is wonderfully malleable. It has been hammered into gold leaf for centuries.
Ductility, the property of a substance to be drawn out into a thin wire is a physical property associated with some metals, such as gold, silver and copper.
The color of gold is a physical characteristic, determined by its interaction with light and the way it reflects and absorbs different wavelengths. It is not a result of any chemical reaction taking place.
