Quintessence Classes · Accepted Answer

The correct answer is VIII. The Correct Reactivity Order (From Most Reactive to Least Reactive):Lithium (VIII) — Most reactive  ScribdCalcium (II)Magnesium (V)Cobalt (IV)Nickel (VI)Silver (III)Gold (I)Platinum (VII) — Least reactive  ScribdExplanation:The reactivity series ranks metals based on how easily they lose electrons to form positive ions.  Chemistry LearnerAlkali and Alkaline Earth Metals (Lithium, Calcium, Magnesium): Sits at the very top of the series because they have a single or double electron in their outermost shell, making them highly reactive with water and acids.Transition Metals (Cobalt, Nickel): Moderately reactive metals that react slowly with acids.Noble Metals (Silver, Gold, Platinum): Found at the very bottom of the reactivity series. They are highly unreactive, do not react easily with oxygen or acids, and Platinum sits at the absolute bottom as the least reactive metal of all.  Chemistry LearnerFollowing this exact chemical sequence yields the order: VIII, II, V, IV, VI, III, I, VII (or VII, I at the very end depending on the specific textbook chart, matching the sequence listed in option B).
