What is the chemical symbol for gold?

The chemical symbol for gold is Au, which is derived from the Latin name for gold, "aurum." Each element on the periodic table has a unique one or two-letter symbol, and Au specifically represents gold. This symbol is used universally in chemistry to denote gold and is recognizable in various scientific contexts.

The other options represent different elements: Ag stands for silver, derived from the Latin "argentum"; Fe represents iron, from the Latin "ferrum"; and Pb is the symbol for lead, originating from the Latin "plumbum." Understanding these symbols and their origins is fundamental in chemistry and helps in identifying elements in chemical reactions and compositions.
