Aluminium
One property of metal foil that makes it a good material to use as a switch is its high electrical conductivity. This property allows for efficient flow of electrical current through the foil, making it an ideal material for conducting electricity in a switch mechanism. Additionally, metal foil is malleable and can be easily shaped or bent to create the desired switch design. Lastly, metal foil is durable and can withstand repeated use without significant degradation, making it a reliable choice for switch applications.
Block foil printing is producing gold (silver) foil printing on a piece of wood.

Gutenburg first invented printing that used separate metal letters.
The metal that is used as a dye in CT scans is water soluble iodine or barium. These are sometimes avoided by patients because of allergies to the metals.

depends on foil:aluminumgold (usually called leaf not foil, most common use is lettering on leather bound books)silver (usually called leaf not foil, most common use is lettering on leather bound books)tin (used for purpose aluminum foil is used for, rarely seen today)lead (often used in roofing to prevent leaks from pooling water, thick for foil)etc.
because aluminum foil is really metal and metal is an element.
Aluminum foil is made of aluminum metal.
Foil is usually made of Aluminum and maybe sometimes some form of steel. Metals like Magnesium or Tungsten wouldn't be used in foil.
What kind of foil? The stuff you get in the supermarket to wrap sandwiches is mostly aluminum (although it contains other elements - both added intentionally and picked up from the recycling process that a lot of aluminum goes through) but "foil" is just paper-thin sheet metal so any metal malleable enough to roll down to a few thousandths of an inch thickness, and strong enough to hold together when it's rolled that thin, can be made into foil. There's gold foil, silver foil, copper foil, tin foil - yes, "tin foil" that's really made out of tin exists - lead foil, iron foil, steel foil...Aluminium is the metal used in foil. Its symbol is Al. Its atomic number is 13.
