Why does silver does not stick to silvers?

Answer 1

I assume you are asking "why doesn't one piece of silver stick to another piece of silver?"

This actually a very interesting question, because, despite what you have observed, one piece of silver will stick to another piece of silver, but only in a vacuum. In a pure vacuum you could take a hunk of silver, cleave it apart, then fuse those pieces back to together simply by having them make contact. However, outside of a vacuum, the silver gets bits of dirt, grease, oil, and other contaminants on it. Even if you could clean all the visible dirt off, there would always be a layer of water, oxyen, and other molecules that collects on the pieces of silver preventing the silver atoms from fully coming into contact with each other. (Not that the atoms every actually make contact, but i feel the description is close enough) This is true with not just silver, but many other metals and materials.
