a. Consider a metal atom, which we will give the symbol M. Metal M can readily form the M+ cation. If the sphere on the left below represents the metal atom M, which of the other three spheres would probably represent the M+ cation? Explain your choice.

b. Consider a nonmetal atom, which we will give the symbol X. The element X is a gas at room temperature and can easily form the X anion. If atom X is represented by the sphere on the left below, which of the other three spheres would probably represent the X anion. Explain your choice.

c. On the basis of the information given previously, write a balanced chemical equation for the reaction that occurs when metal M reacts with nonmetal X. Include state symbols for the reactants and products.
d. Is the product of the reaction of M and X a molecule or an ionic compound? Provide justification for your answer.
e. Which of the representations below is the most appropriate to describe the compound of M and X, according to your answer for part d? Explain how you arrived at your choice.
