With the Introduction to Electron Structure Chemistry Laboratory Kit, several workstation “atoms” are built. An energy level diagram, atom and ion symbols and bingo chips representing electrons help students visualize electron structure.
Help students understand the basics of electron structure with this simple and straightforward lab activity. In this activity, 15 workstation “atoms” are constructed, each consisting of an energy level diagram, a symbol for a neutral atom or ion and bingo chips representing electrons. Students correctly fill the energy levels with the proper number of electrons for each neutral atom or ion. By visualizing the electron energy levels, students gain a better understanding of electron structure. They also learn why atoms tend to become positively or negatively charged as well as the role electrons play in chemical reactions. Includes enough materials to construct 15 workstation “atoms,” reproducible student handouts and Teacher Notes.
Complete for 30 students working in pairs.
