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.

i'm not sure

explanation:

i'll try whatever you got

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

the objects have the same charge.
