Potassium is essential to several aspects of plant, animal, and human life and is thus mined, manufactured, and consumed in huge quantities around the world.

It connects the Gold Rush to gold's unreactiveness, which facilitated extraction, while most elements form reactive ions. Cations from groups 1 and 2 of the periodic table are named after their parent elements with a charge indicated by a superscript. The text emphasizes cations' significance in everyday life, including their functions in the body and uses in water softening and food preservation.
