What is the symbol for calcium?

Calcium is represented by the symbol "Ca" on the periodic table, which comes from the Latin name for calcium, "calx," meaning lime. This symbol is standardized and used universally in scientific contexts. Each element has a unique chemical symbol, typically derived from its name in English or another language, and "Ca" indicates that it is a specific element distinct from others such as chlorine ("Cl"), carbon ("C"), or curium ("Cm"). Recognizing these symbols is crucial for understanding chemical reactions, formulas, and discussing elements in a scientific manner.
