Elements are composed of atoms of one kind only. The periodic table (at www.webelements.com gives a complete list of all of the elements. Elements combine to form compounds (that is, compounds are combinations of two or more elements). Mixtures can be separated by physical means (iron and chalk, for example, can be separated with a magnet) but compounds cannot be separated by physical means; however, they can be separated chemically. I do not know of a microscope that can see electrons, protons, and neutrons although there are devices available that can see the effects of those three particles.
