The Chemistry of Gold
Gold (Au) is a chemical element with the atomic number 79, belonging to Group 11 in the periodic table. It has an atomic mass of 196.9665695 g/mol and is one of the densest naturally occurring elements, with a density of approximately 19.3 g/cm³. Gold’s high melting point (1,064°C or 1,947°F) makes it highly resistant to corrosion and allows it to maintain its luster over time.
Physical Forms of Gold
Gold can be found in various physical forms, including:
- Raw gold : Natural nuggets of pure gold that have not been processed.
