The model of the atom is explored by looking at role and placement of electrons, protons and neutrons in an atom. Questions get students to practice drawing Rutherford-Bohr models of the atom. The role that the gain and loss of electrons have in chemical reactions is also explored which leads to an conclusion about the stability of a full valence electron shell.
