What is the chemical symbol for potassium?

In chemistry, each element has a unique one- or two-letter symbol. Potassium is the element with atomic number 19, and its symbol is K, derived from the Latin Kalium. This is why you’ll see potassium represented as K in formulas like KCl. The other symbols correspond to different elements—Na for sodium, Ca for calcium, and Mg for magnesium—so the symbol for potassium is K.
