Gold Element in Periodic Table | Atomic Number Atomic Mass

Gold Element:

Gold is a chemical element and it is a member of group 11 and period 6 in the periodic table. The atomic number of gold is 79 and it is indicated by symbol Au. Au is a bright, slightly reddish yellow, soft, dense, malleable and ductile metal in its purest form.  It occurs in free element form in veins, rocks and in alluvial deposits. ¹⁹⁷Au is a stable and natural isotope of gold.

Uses of Gold Element:

• Au is used extensively in jewellery, either in its pure form or as an alloy.
• Au is also used for coinage
• Au compound is used to treat arthritis and dentists also use gold alloys in fillings.
