Cutting aluminum foil in half is a physical change. A physical change alters the form of a substance without changing its chemical composition. In this case, the aluminum foil remains aluminum foil after being cut in half, just in two smaller pieces. No new substances are formed during this process, so it is considered a physical change.
Density and Luster.
No but it is made of aluminum which is the most prevalent element in the earth.
aluminum foil
Aluminum foil is not an element as the foil has a small amount of other stuff added to it to make it an alloy. Aluminum element would only have aluminum atoms and no other compounds added to it. An alloy has two or more metals together.
Aluminum and tin are two different elements. They have different physical and chemical properties. Tin is element 50. Aluminum is element 13. Tin is denser and has a lower melting point than aluminum. Tin can reach 2+ and 4+ oxidation states while aluminum can only achieve the 3+ oxidation state.
Physical. It's still aluminum foil.

When aluminum foil is added to copper chloride solution, a chemical reaction occurs where the aluminum replaces the copper in the compound to form aluminum chloride and copper metal. This is a chemical change because the composition of the substances is altered. The physical change that occurs is the color change of the solution from blue to greenish-brown due to the formation of copper metal.

Foil cut into pieces represents a physical change.
A chemical change occurs. When aluminum foil is placed in liquid bromine, the aluminum reacts with bromine to form aluminum bromide, which appears as a white solid. This reaction is a chemical change because the composition of the substances involved is altered.
Beating aluminum to make aluminum foil is a physicalchange, and not a chemical one. Note, however, that aluminum is generally rolled to make foil rather than beaten. The ductility of aluminum is a physical characteristic of this amazing metal that makes it possible for us to do that.
When copper chloride reacts with aluminum foil, a chemical change occurs. This reaction results in the formation of copper metal and aluminum chloride. The color change (from blue to brown/red) and the formation of a solid precipitate are indicators of a chemical reaction taking place.
Tearing a piece of tin foil is a physical change because the substance's chemical composition remains the same before and after tearing. The appearance and physical structure of the tin foil may change, but no new substances are formed during the tearing process.
That would be a chemical property, specifically a chemical reaction. The formation of a white solid (aluminum bromide) indicates a chemical change has occurred as the aluminum has reacted with the bromine to form a new substance.
Iron rusting = chemical gasoline burning = chemical cutting a piece of wood = physical aluminum reacting with foil paper= chemical Anytime the basic molecule is changed, it is chemical, and if it is not than it is physical. Keep in mind that basic state changes (e.g. melting from solid to liquid) are physical.
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.
