Use the table above to answer this question .The least reactive element is

Answer Details

From the reactivity series in the table, the least reactive element is Z. This is because Z is placed at the bottom of the series and is the only element that does not react with any of the other elements. Elements higher up the series are more reactive because they can displace the ions of elements below them in the series. Therefore, since Z is placed at the bottom of the reactivity series and does not react with any of the other elements, it is the least reactive element in the table.
