Not Bronze, Not Silver, But Gold Ben Chasin; 8th Grade; Mrs. Bryan Science F Period

My element is Gold. Gold's symbol on the periodic table is Au. Gold has been used by humans as far back as the Chalcolithic or Bronze Age. It was first discovered as shiny yellow nuggets found in streams. Early artisans of the time period used gold to make jewelry. Golden artifacts have been found in the Balkans that predate the Christian Era by four thousand years. ( Gold gets its English name from the Germanic word gulþa (meaning gold). In Latin, the word for gold is aurum. That is why the symbol for gold on the periodic table is Au.

Gold's atomic number is 79 and it's atomic mass is 196.97. Gold has 79 protons, 79 electrons, and 118 neutrons. Gold only has one stable isotope with 118 neutrons. (This is a man panning for gold)

Gold is primarily found as the pure native metal. Gold usually is found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia, and Canada.

Because gold is so stable and malleable, and can be found in nature, gold was once used to make coins. Because it so expensive, it is rarely used in coins anymore. Gold is used for jewelry because of its attractive color, relative softness, resistance to corrosion and rarity. Gold is also used in dentistry fillings, crowns, bridges and orthodontics because it is chemically inert, nonallergenic, and easy for the dentist to work with.

The boiling point of gold is 3130 degrees C, and the melting point of gold is 1,337.33 degrees C. A fun fact about gold is that in every cubic mile of sea water there is 25 tons of gold. That’s a total of about 10 billion tons of gold in the oceans. (
