The Fascinating World of Gold: Shiny, Rare, and Costly

The video tutorial explores the element gold, its properties, and its significance. Gold, with atomic number 79 and symbol Au, is a transition metal known for its malleability and ductility.

Historically, gold has been used as currency and remains highly valued. However, gold mining poses environmental risks, including cyanide pollution, making it a hazardous endeavor.
