The chemical symbol for potassium, according to the periodic table, is K. The chemical symbol for chlorine is Cl. Potassium readily gives up an electron to chlorine, which readily accepts it. Potassium becomes a cation with a 1+ charge. Chlorine becomes an anion with a 1- charge. These charges balance each other out. The chemical formula for potassium chloride is KCl because it takes one potassium atom to bond with one chlorine atom.
