Question

Why metals dont react with metals?
if they do so , do they form compounds ? If not why?

Answer 1

Metals can react with each other when they are in aqueous solution through redox reactions. Redox stand for reduction-oxidation. Some metals are less reactive than others and based on that, the reactivity series of metals has been made. Less reactive metals tend to oxidise more reactive metals.

For example, if you put a piece of iron in a copper solution, the copper will take electrons from the iron and reduce itself. Thus, solid copper will be produced at the same time iron ions are generated. Take into account that many of these reactions are very slow. There are quicker reactions too, of course.
