Note: A naturally occurring metallic element with symbol K and atomic number 19. Potassium is a soft, silvery-white metal that rapidly oxidizes in moist air. It does not occur in nature in the free state because it is highly reactive. It is found mainly as potassium chloride (sylvite) and in clays (orthoclase, microcline). Major potassium salt deposits include the Great Salt Lake and Salduro Marsh in Utah and the Dead Sea between Israel and Jordan. Potassium salts are used to make fertilizer and hardened glass.

| Chinese (traditional) ..... 一種化學符號為K、原子序號為19的銀白色金屬元素，在空氣中會迅速氧化，必須浸泡在乙醚或煤油中才能保持。鉀可溶於酸性物質及酒精，並會劇烈地分解水。 |
| Dutch ..... Een elementair metaal met het symbool K en atoomnummer 19. Het is zilverwit van kleur, maar oxideert snel wanneer het in contact komt met zuurstof. Het moet bewaard worden in ether of kerosine. Het is oplosbaar in zuren en alcohol en reageert heftig met water. |
| Spanish ..... Metal elemental de símbolo K y peso atómico 39,1. Es de color blanco plateado, pero se oxida rápidamente en el aire y debe mantenerse sumergido en éter o querosén. Es soluble en ácidos y alcohol, y descompone violentamente al agua. |
