Are metals at the bottom of the activity series the most easily oxidized?

• A. True
• B. False
• C. They are least easily oxidized
• D. It depends on the solvent

Answer: (B)

The key idea is that the activity series tells you how easily a metal loses electrons (how easily it is oxidized). Metals that appear high on the list are the ones that oxidize readily; they’re strong reducing agents and will tend to lose electrons in solution. Metals at the bottom are much less prone to oxidation and are considered the least easily oxidized.

So the statement asking if metals at the bottom are the most easily oxidized is opposite to what the activity series shows. The bottom metals resist oxidation and require much stronger driving forces to lose electrons. In practical terms, a high-activity metal can displace a metal ion lower in the series from solution, illustrating its greater tendency to oxidize, while a bottom-metal ion is not easily oxidized under normal conditions.
