Often, scientists who want to demonstrate chemical bonding use models with colored balls to represent atoms. These models are not totally accurate depictions of atoms and molecules, so why do scientists use them? (2 points) Select one: a. The models are useful for scientists who are not able to use real experimental data. b. The models are used as visual representations of something that is not easily seen or observed. c. The models help scientists study atoms without having to conduct experiments or collect data. d. The models allow scientists to predict bonding and reactions without making real life observations.
