Question

    Which of the following metals is placed at the bottom of

    the reactivity series? 
    A Gold Correct Answer Incorrect Answer
    B Potassium Correct Answer Incorrect Answer
    C Mercury Correct Answer Incorrect Answer
    D Iron Correct Answer Incorrect Answer

    Solution

    In chemistry, the reactivity series is a series of metals, in order of reactivity from highest to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series. Noble metals like gold, platinum are low in reactivity and are therefore kept at the bottom in the series. Hence, option A is correct.
