Chemical reaction like rust.
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
a physical property
A chemical property. the tarnished surface is chemically altered to a new compound (silver oxide).
chemical, because when a penny is tarnished its a chemical change because, its weathered down its destroyed. The tarnish itself is usually either the oxide and/or sulfide of the underlying metal.
Oil protects metal from tarnishing by forming a barrier that prevents moisture and oxygen from reaching the surface. This barrier reduces the likelihood of chemical reactions that lead to oxidation and corrosion, which are the primary causes of tarnishing. Additionally, the oil can help repel contaminants and pollutants that might otherwise contribute to the tarnishing process, thereby prolonging the metal's appearance and integrity.

A chemical property. the tarnished surface is chemically altered to a new compound (silver oxide).
It's a chemical change because a new substance comes out of tarnishing.
Chemical.
The ability to tarnish is a chemical property. Tarnishing occurs when a substance undergoes a chemical reaction with other compounds in its environment, leading to the formation of a different substance on its surface.
Tarnishing of silver is a chemical change. It occurs when silver reacts with sulfur-containing substances in the air to form silver sulfide, which is the black tarnish seen on the surface of the metal. This change is irreversible and alters the composition of the silver.

Gold's property of being resistant to oxidation in the air, due to its stability and unreactive nature, prevents it from tarnishing or corroding when exposed to oxygen. This property is known as its inertness towards atmospheric oxygen.
The tarnishing of silver (Ag) is a chemical property because it involves a chemical reaction between silver and sulfur compounds in the air or on the surface of the metal, leading to the formation of a dark layer of silver sulfide on the surface.
Tarnishing is a chemical change as it involves a reaction between the metal and substances in the environment, leading to the formation of a new compound on the metal surface. This new compound is often a metal oxide or sulfide, which gives the tarnished appearance.
Gold does not tarnish. If it's tarnishing it's not real gold.
