Aluminum foil is pure elemental aluminum in very thin sheets. It's a 100%, or, to be more precise, 99.99% aluminum.
depends on the alloy. it can range from 93.0% to 99.7
Aluminum foil is a very cheap substance. Most stores will have aluminum foil on sale for 1 dollar or less.

The composition of aluminum foil is NOT 100% pure aluminum, as many people believe. You may have noticed that aluminum foil always seems dull on one side, and shiny on the other. This is caused by a naturally-occurring reaction. When Aluminum comes into contact with oxygen, the two elements undergo a spontaneous reaction: 4 Al(S) + 3 O2 (G) => 2 Al2O3 (S) The aluminum foil reacts with oxygen in the air to form a thin layer of Aluminum Oxide on one side of the foil. Because rolls of aluminum foil are generally rolled tightly, the inner side of the aluminum foil is not exposed to the air as much, and it remains shiny. In short, the composition of aluminum foil is pure aluminum (Al) AND aluminum oxide (AL2O3). (And don't worry-- the layer of aluminum oxide on aluminum foil is completely harmless. We've been using foil to cover food for years, after all.)
aluminum foil keeps things colder.
Aluminum is element. Aluminum foil is made entirely of aluminum.
Aluminum foil is made of Aluminum, which is an element. So yes Aluminum foil is a element

Tin foil... tin Aluminum foil... aluminum :)
Because all aluminum foil is not equal. Aluminum foil is available in a variety of thicknesses.
Only a single component makes up aluminum foil, which is the aluminum element. Hence, aluminum foil is considered as a pure substance.
