Question

Statement 1: It is easier to extract the metals that are present at the top of the reactivity series.
Statement 2: Metals at the top of the reactivity series are highly reactive in comparison with the metals at the bottom.

• A. Both statements are true.
• B. Both statements are false.
• C. Only statement 1 is true.
• D. Only statement 2 is true.

Answer 1

The correct option is D Only statement 2 is true.

The metals at the top of the reactivity series (K, Na, Ca, Mg and Al) are so reactive that they are never found in nature as free elements. It is difficult to separate them from their compounds and extract.

The metals at the bottom of the reactivity series are the least reactive. Some of these metals are found in the earth’s crust in their free state.
For example, gold, silver, platinum and copper are found in free state. So, it becomes comparatively easier to extract such least reactive metals.
