1/23/2024 0 Comments Gold element periodic table![]() ![]() Gold is so malleable and ductile, that an ounce can be beaten into a sheet covering 300 square feet or drawn into a wire 60 miles long.No one knows who discovered Gold, but the first Gold coins as currency appeared in Turkey under King Croesus of Lydia around 550 B.C.18 karat Gold is 75% pure and 12 karat is 50% pure Gold. ![]() Pure Gold is 24 karat, which translates to.Gold density decreases after melting to 17.31 g/cm3. The density of Gold at room temperature is 19.30 g/cm3. In its pure form, it is bright, slightly reddish-yellow in color and malleable.The melting point of Gold is a sizzling 1,948☏.The molar mass of Gold is 196.967 g/mol.The Gold atomic number is 79, which is the number of protons (positively charged particles) in the nucleus.The Gold symbol “Au” comes from the Latin word “aurum,” which means “shining dawn.” Shared properties with the Gold element include being inert, corrosion-resistant metals with low electrical resistivity. These metals are great for circulation because they have excellent wear resistance. The Gold periodic table placement is in period 6 (horizontal row) and family 11 (vertical column), along with other coinage metals like Silver and Copper. In the periodic table, elements are grouped according to electronic structure. Learn about todays Gold spot price and other Precious Metals with APMEX. Gold’s unique elemental properties give it a special luster, durability, malleability and aversion to rust and erosion that make it one of the most sought-after metals in the world. It is estimated that roughly 165,000 metric tons of Gold have been mined throughout history. ![]() According to Gold historian Timothy Green, Gold has been mined for more than 6,000 years. Our fascination with Gold existed long before 2013. Most of what is here are thought to have arrived with asteroids and meteorites. It is often found as nuggets or particles in the beds of streams. On Earth, however, Gold only exists in the crust at 5 parts per billion. Calculations suggest the explosion produced 20 Earth-masses worth of Gold. After the brief flash of light, astronomers observed radioactive afterglow that produced huge quantities of heavy metals, like Gold. In 2013, scientists discovered evidence that suggests Gold comes from the collisions of ultra-dense objects called neutron stars after witnessing a short gamma-ray burst (GRB) 3.9 billion light-years away. ![]()
