Gold’s Uses Gold is often crafted into different jewelry which is the most common use of gold. Other common use of gold is in the making of trophies and medals most commonly found in the Olympic medals. At one point in time gold was the most common currency.

Gold’s History To the Incas gold was often referred to as “The Sun’s tears” Gold was first discovered in it’s most common form, nuggets. Gold was and still is the most sought after mineral for most humans.

Gold’s Isotopes Gold only has one stable isotope which is 197 Au Gold also has 36 radioisotopes which are 195 Au

Other Interesting Facts The word “gold” comes from the Proto-Indo-Eruopean ghel/ghol which means “yellow”, “green” or possibly “bright”. It is commonly used in wiring for sound equipment. For some people it is also called “Butter”.
