Gold (Au)
Gold is found as a free metal in nature, occurs in veins and alluvial deposits, and is associated with tellurides, quartz, and pyrite.
In pure form, it's an attractive metallic yellow color, but can be black, ruby, or purple in smaller quantities. As the most malleable and ductile metal, gold is typically alloyed for strength. It conducts heat and electricity, reflects infrared rays, and is mostly unaffected by air and chemicals. Some of gold's 18 isotopes are used in medicine to treat cancer and arthritis.
