Do metals react with each other?
I know this is kinda cheating, but I need some help with my science homework and my parents don't know anything. I can't find a definitive answer on the internet anywhere so I thought I'd try here.
Metals have delocalised electrons and this forms the metallic bond, but can metals react with each other? It's not possible to have a negatively charged metal so I'm assuming they can't, but it'd be nice if someone could confirm or correct me.

Thank you SO much for that guys. Greatly appreciated.

There is no chemical reaction between two metals since there is not an effective way to transfer electrons. Maybe a Carbon Buffer or something, but nothing really.

No, they can't react with each other. Magnetism does not count since it is a force (as already explained). Electrolysis doesn't count either since it typically involves a metal-nonmetal solution and makes use of an electric current to oxidide the metal and the reduce the non metal ions. The metal does not react with the cathode but rather takes electron(s) from it that have passed through the electric circuit (which were first donated by the nonmatel at the cathode.

[quote][b]Posted by:[/b] Glopaticki I remember in my engineering class when two metals varying in the galvanic series are put together, one would form the anode and corrode where as the other would form the cathode and be safe from corrosion. Its a way they protect ships hulls i think[/quote] I think they use magnesium for that. I have to get my Chemistry books and read through them.

Two metals cannot chemically react because they have the same charge and therefore there is no attraction between them for them to bond with.

As far as I can remember, no solid object can react with another solid object, they may react where the connection is, but that is such a small small area that it's not noticable. To get something to react, they have to be in liquid form. You can't make Ethanol from frozen Ethane and frozen Oxidating (Putting in an O) I think.

metals dont react...

Nope. A chemical reaction is to do with the electrons. Melting something down is called a physical change as it doesn't actually change the chemical make of an element or substance.

Alloys?
