Question

Potassium is never found in nature as free element because:

• A. Potassium is present at the top of the activity series.
• B. Potassium is present at the bottom of the activity series.
• C. Potassium is present in the middle of the activity series.
• D. Potassium is an unreactive metal

Answer 1

The correct option is A

Potassium is present at the top of the activity series.

The elements which are present at the top of the activity series are most reactive. Therefore these elements combine rigorously with other elements and are generally found as compounds. Potassium is placed in the top part of the activity series.
