Question

A list of common metals arranged in order of their decreasing reactivity is known as:

• A. activity series
• B. reactivity series
• C. conductivity series
• D. both $A$ and $B$

Answer 1

Answer: (D)

both $A$ and $B$

An activity or reactivity series is a list of substances ranked in order of relative reactivity formed after displacement experiments. The most active metals are at the top of the table and least reactive at the bottom of the table.
