What are the relative masses of the three main subatomic particles? (Assume the mass of a proton is 1.) * A. Proton = 1, neutron = 1.5, electron = 0.5
B. Proton = 1, neutron = 1, electron = 1
C. Proton = 1, neutron = 1.25, electron = 0.25
D. Proton = 1, neutron = 1, electron = 1/1840

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.
