Science Bethany observes a white crystal that is cube shaped under a microscope. a Model of Crystal Structure Based on this observation, Bethany thinks the crystal could be sodium chloride, or table salt. Because the crystal has an extended structure, she knows that sodium chloride is not a molecule. Bethany uses gray and white spheres, representing the atoms in sodium chloride, to make a model of the crystal's most likely structure, as shown. a Provide two reasons why the model accurately represents sodium chloride. Support your reasons with evidence from the model.
