In this simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. The simulation visually differentiates between the transferring of electrons when forming an ionic compound and the sharing of electrons when forming a covalent compound so that students can have a complete understanding of each. Finally, students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.
