Imagine a substance that's both a mineral and an electrolyte which helps our most important muscles work, like the ones that control our heartbeat and breathing. Oh wait, that's Potassium! What is the chemical symbol for Potassium?

Potassium is a soft, silvery-white metal naturally found in the foods we eat such as bananas, oranges, cantaloupe, prunes, and apricots. The K comes from its Neo-Latin root "kalium".
