Message definition (Potassium)
Potassium is chemically very similar to [[sodium]], the previous element in [[Group (periodic table)|group]] 1 of the periodic table. They have a similar first [[ionization energy]], which allows for each atom to give up its sole outer electron. It was first suggested in 1702 that they were distinct elements that combine with the same anions to make similar salts, which was demonstrated in 1807 when elemental potassium was first isolated via [[electrolysis]]. Naturally occurring potassium is composed of three [[isotope]]s, of which [[potassium-40|{{chem|40|K}}]] is [[radioactive]]. Traces of {{chem|40|K}} are found in all potassium, and it is the most common [[radioisotope]] in the human body.
