Answer 2

Explanation:

                     In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water, double displacement reactions and the extraction of metals from their ores.

        Sodium is a highly reactive chemical element . Sodium is located at the highest  position of  most reacting chemical elements in the reactivity series  with other elements having high reactivity .

But , Silver is a very inactive metal and doesn't react easily and quickly . Silver is located at the position lowest position of least or feebly  reacting chemical elements in the reactivity series with other elements having low reactivity .

Hence Sodium (Na) is highly reactive than the Silver (Ag) . Therefore Sodium is located many positions above Silver in the reactivity series .
