Old Church Slavonic zlato, Russian zoloto, Sanskrit hiranyam, Old Persian daraniya-, Avestan zaranya- "gold;" see Chloe).

- A soft yellow element that resists corrosion and is the most malleable and ductile metal, used to treat rheumatoid arthritis and intravenously in liver imaging. Atomic number 79.
- A soft, shiny, yellow element that is the most malleable of all the metals. It occurs in veins and in alluvial deposits. Because it is very durable, resistant to corrosion, and a good conductor of heat and electricity, gold is used as a plated coating on electrical and mechanical components. It is also an international monetary standard and is used in jewelry and for decoration. Atomic number 79; atomic weight 196.967; melting point 1,063.0°C; boiling point 2,966.0°C; specific gravity 19.32; valence 1, 3. See Periodic Table. See Note at element.
