Now build a model of salt. Place your materials on a sheet of paper. The regular-size marshmallows can represent the larger chlorine atoms, and the mini marshmallows can represent the smaller sodium atoms. Connect the marshmallows with toothpicks using the picture as a guide. What was difficult about building the model?
