Alkali earth metals exhibit the following except a. They react by losing two electrons b. Their cations react with anions of Group 6A to form metal oxides c. They are never found uncombined in nature. d. These metals react with base to form hydrogen gas.     If a copper-plated iron can is scratched, the iron beneath it corrodes more rapidly than it would without the coating. On the other hand, a galvanized iron can is not oxidized if its coating is scratched. Which statement below about these processes is false?  a. Zinc is preferentially reduced b. Zinc is acting as a sacrificial anode. c. Copper is less active than iron d. Zinc is more active than iron.
