The chemical symbol for chlorine is Cl.
Understanding Chemical Symbols
Chemical symbols serve as a universal shorthand in chemistry, representing elements succinctly across languages and scientific disciplines. These symbols are typically derived from the element's English name or its Latin equivalent, often consisting of one or two letters. The first letter is always capitalized, while the second (if present) is lowercase. This standardization, maintained by organizations like the International Union of Pure and Applied Chemistry (IUPAC), ensures clarity and consistency in scientific communication worldwide.
