components are represented, including the nucleus; the particles
that constitute the atom including the protons, neutrons and
electrons; and the electron layers. Facilitates clear
comprehension of the atom's structure and such important concepts
as atomic number, electroneutrality, the filling of electron
layers and the definition and calculation of ionic load. Durable,
plastic model is transparent for convenient use with an overhead
projector. Includes comprehensive teacher's guide.
