The Atom when it was first discovered both pleased and puzzled scientists. The atom is the basic unit of matter. It has a central nucleus with a cloud of electrons. An innovation recently found about the atom is that we never really touch the surface of something. The atom is protected by electrons, which means it is the shell of electrons that our touch interacts with, not the real surface of an object.
The atom is a fascinating piece of the world, since all things are made of matter. The amount of electromagnetic force the atom has will depend on the type of compound or molecule that it is. For example an atom can be neutral because it has an equal number of protons and electrons.
