What is the chemical symbol for potassium?

• A. Na
• B. Fe
• C. Ca
• D. K

Answer: (D)

The chemical symbol for potassium is derived from its Latin name, "kalium," which is why the symbol is "K." This symbol is used in the periodic table to represent potassium, an essential element that plays various critical roles in biological systems, such as nerve function and fluid balance in the body. Each element on the periodic table has a unique one- or two-letter symbol, and potassium is specifically identified by the letter "K" to avoid confusion with other elements. The other choices represent different chemical elements: "Na" is the symbol for sodium, "Fe" stands for iron, and "Ca" represents calcium. Each of these elements has its own specific characteristics and uses, distinct from potassium. Thus, knowing and correctly identifying the symbol for potassium is important in chemistry and various scientific applications.
