![]() At 180 ☌, the powdered form of gold reacts with chlorine and forms AuCl 3.Gold reacts with fluorine at higher temperature and forms gold (III) fluoride. Gold does not react with oxygen even at higher temperature, but it does react with strong halogen like fluorine.But the most common oxidation states of gold are +1 and +3. The oxidation states of gold range from -1 to +5.Gold is a non reactive metal and it does not corrode or tarnish in the air.Chemical properties of GoldĬhemical properties of gold are mentioned below. The crystal structure of gold is FCC (face centered cubic).Gold has many isotopes and out of the naturally occurring isotopes, 197Au is the most abundant (almost 100%).The melting point of gold is 1064 ☌ and its boiling point is 2970 ☌.The atomic mass of gold is 196.97 u and its density is 19.3 g/cm 3.Gold is also a good conductor of heat and electricity.Hence it can be drawn into thin wires as well as it can also be stretched into thin sheets. Gold is a ductile as well as malleable metal.Gold is a precious metal having yellow metallic lustre.Physical properties of gold are mentioned below. The physical and chemical properties of gold element are mentioned below. Apart from the earth’s crust, gold is also available from the oceans.Gold is one of the elements that is known to humans since ancient times (before 6000 BCE).Approximately 78% of the total gold produced in the world goes to the manufacturing of jewelry.South Africa is the leading producer of gold and it produces around 2/3 rd of the total gold production in the world.The symbol of gold is Au, which came from the latin word for gold “aurum”.Interesting facts about gold element are mentioned below. Hence, according to the definition mentioned above, gold is a transition metal. In short, gold element have incomplete d-orbitals in its oxidation state (Au 3+). You can see that all the d-orbitals are completely filled (all the 10 electrons are present) in the elemental state (Au) but they are incomplete (only 9 electrons are present) in its oxidation state (Au 3+). Protons in Gold 79 Neutrons in Gold 118 Electrons in Gold 79 Symbol of Gold Au Atomic mass of GoldĢ, 8, 18, 32, 18, 1 Electronic configuration of Gold 4f 14 5d 10 6s 1 Atomic radius of Goldġ66 picometers (van der Waals radius) 1st Ionization energy of Gold 9.226 eV Electronegativity of GoldĢ.54 (Pauling scale) Crystal structure of GoldįCC (face centered cubic) Melting point of Gold 1337 K or 1064 ☌ or 1947 ☏ Boiling point of Gold 3243 K or 2970 ☌ or 5378 ☏ Density of Gold 19.3 g/cm 3 Main isotope of Gold 197Au CAS number ![]() Transition metals Atomic number of Gold, or Group: 11, Period: 6, Block: d Category of Gold element Metallic yellow State of Gold at STP Solid Position of Gold in Periodic table Gold Element (Au) Information Appearance of Gold So if you want to know anything about Gold element, then this guide is for you. In fact, the table mentioned below is the perfect information box (Which gives you every single detail about the Gold element in Periodic table.) It is a solid metal at room temperature with a melting point of 1064°c and a boiling point of 2700°c.This is a SUPER easy guide on Gold element. It was also the focus of the work of many alchemists who believed they could make gold by mixing mercury and sulfur. Gold was prized by the Egyptians and Romans. It’s exact discovery is unknown but it can be traced back to Bulgaria in the year 4500BC where a number of gold objects were crafted. Gold is a metal that has been treasured by humans for years. Gold flake has been used in food production and is safe to eat. It is also used as a heat shield on space craft due to its excellent reflective ability. Gold is used in coins and jewelry due to its malleability and attractive colour. It is often purified using cyanide and mercury meaning its production produces a lot of waste. Gold is a precious metal that is found uncombined and naturally in the earth’s crust. Gold (Au) is a soft gold coloured metal that has the atomic number 79 in the periodic table.
