In chemistry I learned that everything is either mixture, compound or
element. Later of course I learned about nuclear particles, but that doesn't
apply here. So is Amalgam a mixture in which different elements are put
together so that the different elements stack together very neatly, but not
chemically bonded OR is it a compound where the atoms share electron orbits
and no free atoms can come off without a chemical reaction. I think alloys
by definition are mixtures but I may be wrong.
