chemical symbol
The term 'símbolo químico' refers to a code for a chemical element. This symbol usually consists of one or two letters derived from either the element's current name or its original Latin or Greek name. For example, 'H' is the chemical symbol for Hydrogen, 'Au' for Gold which stems from its Latin name 'Aurum'. Thus, these chemical symbols serve as universal annotations for chemical elements, widely used in scientific contexts.
