A scanning electron microscope is a tool that uses electrons to make very sharp images with magnification of up to
500,000x. Our knowledge of electrons comes from early study of the atom that lead to greater understanding not
only of electrons and atomic structure, but of the nature of all particles. This chapter covers modeling the atom and
atomic spectra, the Bohr atom, and the Uncertainty Principle.
