It is not clear from your question what you mean by sharing substances, or exactly what it is that these substances are sharing. However, I'll make a guess. Chemical reactions often involve atoms sharing electrons. And what happens to them during chemical reactions is that the distribution of electrons shifts. Electrons don't have to actually leave one atom and go to another in order to form a chemical reaction. Sometimes it is more a matter of spending some time with one atom and some time with another, or with several others. Electrons are very versatile.
no chemical reaction takes place . when electrons are shared it is known as covalent bond
Gold wouldn't corrode, I think that's what you mean because generally speaking metals don't dissolve. Corrosion is a chemical reaction where as dissolving is, I would say, more of a physical change because electrons aren't shared or exchanged in the process.Also platinum wouldn't.
In a covalent bond electrons are shared between two electrons.
Partners are exchanged in a double replacement reaction.
Electrons Are Exchanged

They are lost.
Matter is simply rearranged, atoms are exchanged to create new molecules.
They are the electrons in the (outer) valence shell
It really does depend what the electrolyte is. However, as electrons are basically being exchanged the reaction is a REDOX one.

A chemical reaction
The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
