Scientists at a metallurgic factory are testing different metals to study the strength of the electrical forces between their atoms. They determined the force needed to bend a sheet of each metal and found that Metal A requires 50 N of force, Metal B requires 30 N, Metal C requires 70 N, and Metal D requires 100 N. Which metal will have the lowest melting point? a A b B c C d D

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.
