Which of the following statements is true about the reactivity series of metals?
-
A.
It is a list of metals arranged in order of their decreasing atomic numbers.
-
B.
It is a list of metals arranged in order of their decreasing reactivity.
-
C.
It is a list of metals arranged in order of their increasing reactivity.
-
D.
It is a list of metals arranged in order of their increasing atomic masses.
Correct Answer:
B. It is a list of metals arranged in order of their decreasing reactivity.
Explanation:
The reactivity series is an analytical tool used in chemistry to rank metals according to their chemical vigor. It organizes elements in descending order of their ability to displace other metals or react with substances like water and acids. By placing the most chemically active metals at the top and the least active at the bottom, this series allows scientists to predict how different metals will behave during chemical reactions based on their relative positions.
