Use the given reactions to answer question 4. Zn + Cu(NO3)2 → Zn(NO3)2 + Cu Zn + Pb(NO3)2 → Zn(NO3)2 + Pb Zn + NaNO3 → No Reaction Pb + Cu(NO3)2 → Pb(NO3)2 + Cu Which of these ranks the metals from most reactive to least reactive?


From most reactive to least reactive, metals can be represented by Cu(NO3)2 + Zn + Cu Zn (NO3) 2. The best answer is A. Let's explore the four most reactive metals. Explanation: The group of alkali metals includes lithium, sodium, potassium, rubidium, cesium, and francium (Fr). The reactivity of these metals increases as you go down the periodic table, as the nuclei gain more electrons and protons, resulting in more electron levels and reducing the electrostatic force of the metals. An example of a reactive metal: Reactive metals belong to a class of metal elements that can react vigorously with acids, water, mineral acids, and potent oxidizing acids. These metals can be identified by their activity or reactivity series, which ranks the most reactive metals in increasing order of reactivity.
