Creatively illustrate atomic number and mass, isotopes, and electron configuration with our magnetic demonstrator. While they physically maneuver the protons, electrons, and neutrons, students can easily visualize how electron levels fill as atomic number changes, how atomic number and mass are calculated, and how ions or isotopes form. The demonstrators are ideal for individual study, or use multiple sets for group learning and team review competitions. Contains: magnets to make 10 red (+) protons, 10 blue (-) electrons, 10 green neutrons, 1 powder-coated steel background and reproducible key sheet. Size: 15 3/4″ x 15 3/4″.
