As of 2016, the world's largest gold producer by far was China with 450 tonnes.Gold is the most malleable of all metals; a single gram can be beaten into a sheet of 1 square meter, and an avoirdupois ounce into 300 square feet.Hans' second LP, Welcome to the Bay, dives straight into the jazzy/hip-hop genre that captures both emotional and technical aspects of the music.From smooth soulful tracks, to jazzy-trap music, Welcome to the Bay has it all. I love the low-key, chill jazz melody and exceptionally smooth rap combination that seemed to come together perfectly in this.Fourteen- and eighteen-karat gold alloys with silver alone appear greenish-yellow and are referred to as green gold.Blue gold can be made by alloying with iron, and purple gold can be made by alloying with aluminium.Gold is resistant to most acids, though it does dissolve in aqua regia, a mixture of nitric acid and hydrochloric acid, which forms a soluble tetrachloroaurate anion.Gold is insoluble in nitric acid, which dissolves silver and base metals, a property that has long been used to refine gold and to confirm the presence of gold in metallic objects, giving rise to the term acid test.

Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars, and to have been present in the dust from which the Solar System formed.

Because the Earth was molten when it was formed, almost all of the gold present in the early Earth probably sank into the planetary core.

Therefore, most of the gold that is in the Earth's crust and mantle is thought to have been delivered to Earth later, by asteroid impacts during the Late Heavy Bombardment, about 4 billion years ago.

The most stable of these is The production of gold from a more common element, such as lead, has long been a subject of human inquiry, and the ancient and medieval discipline of alchemy often focused on it; however, the transmutation of the chemical elements did not become possible until the understanding of nuclear physics in the 20th century.

The first synthesis of gold was conducted by Japanese physicist Hantaro Nagaoka, who synthesized gold from mercury in 1924 by neutron bombardment.

  1. GOLD has proven success in virtual screening, lead optimisation, and identifying the correct binding mode of active molecules. Comprehensively validated and widely used, GOLD enables you to make confident binding mode predictions, and achieve high database enrichments. GOLD reliably identifies the correct binding.
