For each part draw both the the cation and the anions as standalone ions. For each organic ion, draw just the most common Lewis structure, and do not draw alternative resonance forms. You can't put brackets and an overall charge in the answer. instead put the formal charge on each atom in the structure which should add up to the charge on the ion1.Calcium carbonate2.Magnesium hydroxide

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.
