Gold: Element Properties And Uses
Description
Gold is an element that exhibits a bright appearance and defined chemical and physical properties. It is used in industrial, artistic and technical applications.
Introduction to the Element
Gold, with the chemical symbol Au, is a naturally occurring element that has been studied for thousands of years. Past societies used it in art, currency and scientific research. Its specific properties and cultural significance have led to its use in contemporary technology and industry.
Description of Chemical Properties
Gold exhibits chemical inertness. It does not react with many aggressive chemicals and is resistant to oxidation and corrosion. It retains its shine for extended periods, thereby making it suitable for use in high-precision electronics and decorative arts.
In addition, gold can be formed into extremely thin sheets because of its notable malleability and ductility. Its electron configuration contributes to its characteristic appearance.
