And also whats the difference between Metal Gear Solid 2: Substance and the normal one?
Weak. It would corrode from the inside out. Galvanic corrosion. Might be able to make some kind of battery from it though.
Probably not too tough if you cooked it in water at 600 degrees F for about four billion years.
The many different atoms of metal would disrupt the orderly pattern of metal cations, resulting in the formation of a very tough alloy that is difficult to change shape. In other words, yes, it would become very, very tough. =)
Metals can be: a) so reactive they would react with air in an exothermic reaction releasing enough heat to ignite the air around us (but not sodium) b) radioactive and hence decay (some really fast) c) not all that stable (some only exists for less than 1 second [see (b)] d) liquid at room temp. (Hg - Mercury) plus a host of other reasons causing the sheet to be imipossible.
If you mixed every metal known to man into one sheet it would burst into flame. It wouldn't be tough at all, it would only exist as metal oxides. You need to understand that metals like sodium will burst into flame if you expose them to normal air. The heat from burning sodium is more than enough to ignite metals like magnesium. The heat from burning magnesium is more than enough to ignite metals like aluminium. The heat from burning aluminium is enough to ignite metals like iron. Congratulations, you have just created a sheet of thermite. Good going. I get the impresison that you don't understand what a metal actually is, or just how reactive the vast majority of metals are.
