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.

Electron Microscopy Sciences Gold Particles On Carbon Film
This high resolution TEM test specimen is an arrangement of finely-dispersed thin gold particles on carbon film. Image quality, magnification, and instrument stability are readily assessed. For the determination of resolution capabilities this gold particle specimen is superior to gold foil since it offers a choice of crystalline orientation on static or low tilt stages. In addition, the thickness of the crystalline material is easily calculated from the projected shape of the gold crystal. The background noise arising from structure in the support film helps with determinations of the operating transfer function.
