Káliumnak

Káliumnak in Hungarian is the dative singular form of kálium, the word for the chemical element potassium. In grammar, it marks the indirect object or recipient in a sentence, typically with the suffixes nak/nek and, when used with a definite article, in phrases such as "a káliumnak." For example: "A káliumnak fontos szerepe van a szervezetben." This form is part of the broader Hungarian case system, which uses various endings to indicate grammatical relations.

Kálium is a silvery alkali metal with the chemical symbol K and atomic number 19. It is essential for many biological processes, including nerve impulse transmission and muscle function. In nutrition, potassium is usually consumed as part of a balanced diet, with daily requirements varying by age and sex but amounting to several grams for adults. Deficiency can affect cardiovascular and muscular function, while excessive intake or impaired kidney function can lead to hyperkalemia. Potassium is typically absorbed from foods such as fruits (especially bananas), vegetables, milk, and legumes.

In industry, kálium compounds are widespread and play a central role in fertilizers (potassium salts), as well as in chemicals like potassium hydroxide and potassium carbonate. The element occurs naturally in minerals and salts and is recovered from potash and other evaporite deposits. Its name in Hungarian, kálium, derives from the Latin Kalium, borrowed through other European languages.

Overall, káliumnak serves as the grammatical form used in Hungarian to refer to potassium in indirect-object contexts, while the element itself is a crucial mineral for living organisms and a key component of various industrial processes.
