Contrast the structures of ionic compounds and metals. 2. Explain how the conductivity of electricity and the high boiling points of metals are explained by metallic bonding. 3. Contrast the cause of the attraction in ionic bonds and metallic bonds.

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.
