items made of what are the least biodegradable?
Tin foil, so called, is these days more likely to be aluminum foil. This is because aluminum is much cheaper, and is adequate for the purpose. Both metals will degrade in the long time, but whether by biota (biodegradable) or by chemical means (corrosion) is probably immaterial. Tin tends to be toxic to many biota, hence the use of tributyl tin in anti-fouling paints on boat hulls. These have a widespread destructive effect on their local environment. Which is now considered undesirable.
Aluminum is absolutely not made of tin. Aluminum and tin are two separate elements.
An item that is not biodegradable is something that cannot be easily broken down by living organisms. A usual can is aluminum and this material is not biodegradable.
Tin is a non-biodegradable substance, meaning it does not break down naturally in the environment over time. It can persist in the environment for a long period, potentially causing harm if not properly managed.
No. Aluminum will degrade faster than most metals, especially if it is left in salt water, such as at the bottom of the ocean. This is true. Aluminum foil is not biodegradable. your welcome, : )
Tin foil... tin Aluminum foil... aluminum :)
I believe Gallium
Old style steel ("tin") cans were, but modern aluminum cans, no. Steel eventually rusts away, but the oxides of aluminum are more durable than aluminum itself (in fact, they're used as abrasives, to wear away other stuff). On the other hand, recycling aluminum can is twenty times as efficient as extracting aluminum from bauxite ore.

Tin foil usually refers to aluminum foil, which is considered a compound. It is considered a compound because even though it contains at least 80% aluminum, it usually has other components mixed in with it for durability and appearance.
