scope note
  • 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. (nl)
  • 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. (en)
  • 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. (es)
