Metal to degrade?

It depends on the quality, but a tin can takes 50 years, so it takes a long time.

Metals have luster ,they are electric and heat conductors , moreover they have high melting and boiling points.This properties will distinguish it from nonmetals.

Any metal that is in its elemental form is considered metal. A substance that contains a metal in its ionized form is considered a salt.

Metallic elements tend to have similar physical characteristics; they are ductile, malleable, electrically and thermally conductive, solid at room temperature (except mercury) and have very high...

ahhh, but a metal IS a metal.A metal is a metal because it is malleable, shiny, and ductile (can be drawn into wire). It can conduct electricity, and magnetism.A non-metal is brittle, dull or...
