Experiment 1 Rank the metals in terms of their reactivity from most reactive least reactive. Claim 1: Most Reactive Least Reactive Rank the metal in terms of their reactivity from most reactive least reactive. Claim 2: ions Most Reactive Least Reactive Are there any connections between the trends you observed in Claim 1 and Claim 2? Connection: Draw a picture at the atomic level of the reaction between the Zn metal bar and Mental Model: Cu2+ ions in solution. Show electron transfer at the Zn metal surface.
