Kálium

Kálium is the Latin name for the chemical element Potassium. Potassium is a chemical element with the symbol K and atomic number 19. It is a soft, silvery-white alkali metal that is highly reactive. Potassium is found in abundance in the Earth's crust, primarily in mineral salts. It is an essential nutrient for both plants and animals, playing a crucial role in cell function, nerve signaling, and muscle contraction. In plants, potassium is vital for photosynthesis, water regulation, and enzyme activation. In humans, it helps maintain fluid balance, blood pressure, and is involved in more than 60 enzymatic reactions. Due to its high reactivity, pure potassium is not found naturally in its elemental form. It is typically found combined with other elements in compounds. Potassium compounds are widely used in fertilizers, soaps, dyes, and as components in various industrial processes. A common dietary source of potassium is bananas, though it is also present in many other fruits, vegetables, and dairy products. Potassium is also an important electrolyte in the human body.
