Thread: Metallic bonds

I know Metal bonds in such a way that electrons flow relatively freely through out the object, so what stoppes metal wire from fusing when you fold it over?

You appear to be asking about fusion, really.
Nuclear fusion - Wikipedia, the free encyclopedia

Fusing is just another term for “melting”.

True. But since he asked about atomic movement... Either way, the electrons are exchanged, not fused and the exchange of free electrons does not fuse either atoms or metal.

By fusing, you mean creating bonds, yes?

You can create new bonds in metal, but you have to apply energy because bonds are simply stored energy. If you hammer metal together enough or heat it up, you certainly can create new bonds. Simply touching the material to itself is not energetic enough to build new bonds in metal.

sorry, fusing was probably a bad word to use. Thank you Flick, that answered my question.
that said, would the electrons flow between three or four sheets of say... iron stalked on top of one another?

In general, electrons move, or "flow" either from an area having an excess of them, or to an area having a deficiency of them. When they are "on the move", they constitute a flow of electric current. An example exactly like your "stacking" question exists in alternating current transformer cores, which consist of stacks of thin iron sheet, the surfaces of which are intended to LIMIT transfer of electrons between them, which occurs due to the alternating magnetization of the core. The electrons which DO manage to get through, cause the core to be essentially a hunk of short-circuited iron, which condition creates unwanted heat, a loss wished to be minimized.

Edit: The core material is commonly known as "silicon steel".
