How Many Protons, Neutrons, and Electrons Are in Common Elements?
ES0501  Atomic Models

While various types of microscopes can reveal details at many levels of magnification, no microscope can produce images showing the detailed parts of single atoms. For understanding atoms at this level, we traditionally use models instead of actual images.

The models presented in this investigation show a highly simplified view of atoms, but they serve the purpose of allowing us to examine the number of protons, neutrons, and electrons in common elements.
