4.Both xenon (Xe) and argon (Ar) are monoatomic noble gases. Watson predicts that Xe is a liquid and Ar is a gas at atmospheric pressure and a temperature of 120 K. Crick states that both should be gases. Upon reviewing the literature, it turns out that Watson is correct. Explain why Watson is correct and propose the principles that Crick was using to make his prediction.

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.

since electrons are negative the answer is neagtaive
