Understand that the activity series of metals is a list that ranks metals based on their reactivity, especially their tendency to lose electrons and form positive ions.
Recall that metals higher in the activity series are more reactive because they more readily undergo oxidation (lose electrons) compared to metals lower in the series.
Identify the metals given in the problem: Iron (Fe), Silver (Ag), Potassium (K), and Copper (Cu).
Compare their positions in the activity series: Potassium (K) is an alkali metal and is known to be very reactive, typically placed near the top of the activity series, while Iron, Copper, and Silver are lower in reactivity.
Conclude that Potassium (K) is the most reactive metal among the options because it is higher in the activity series, meaning it more readily loses electrons and reacts compared to Iron, Copper, and Silver.
