The chloride ion CI is?

Question

a. less reactive than the chlorine molecule CI 2

b. more reactive than the chlorine molecule CI 2

c. equal in reactivity to the chlorine molecule CI 2

d. any of these choices, depending on the temperature

Answer 1

more reactive

Answer 2

B. Its diatomic, therefore its reactivity increases.

Answer 3

[Quick answer:

Chloride prefers to be in its diatomic form, Cl2, because it's a gas and because Cl by itself has 7 valence electrons.  It wants an extra electron so it can fulfill its octet, so it does this by joining with another Cl atom to form Cl2.

Therefore, a Cl atom/ Cl- ion by itself is definitely MORE reactive than the chlorine molecule Cl2.

[Answer: B]
