You are given a small bar of an unknown metal, x. you find the density of the metal to be 10.5 g/cm cubed. an x ray diffraction experiment measures the edge of the unit cell as 409 pm. assuming that the metal crystallizes in a face centered cubic lattice, what is xef4non most likely to be? why?

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.

0.88m hope i am correct : )
