Gold is a highly sought-after chemical element with the symbol Au (derived from Latin: aurum) and atomic number 79, classifying it as one of the higher atomic number elements found naturally. Its purest form displays an exceptionally bright, slightly reddish yellow color, characterized by being dense, soft, malleable, and ductile. Chemically speaking, gold is classified as a transition metal within group 11, demonstrating remarkable inertness with an astonishing ability to resist most chemical reactions under standard conditions. It often occurs in its pure state, as nuggets or grains, embedded in rocks, veins, and alluvial deposits. Resilient to the corrosive effects of acids, gold exhibits distinct behaviors towards certain acid mixtures; it dissolves effortlessly in aqua regia (a solution composed of nitric acid and hydrochloric acid), generating a highly soluble tetrachloroaurate anion. However, gold resists dissolution in nitric acid alone, distinguishing it from base metals like silver. Additionally, its insolubility is also noted when exposed to cyanide-based alkaline solutions or dissolved within mercury's amalgam alloys – albeit this doesn't qualify as a true chemical reaction. Due to its distinct physical properties and remarkable reactivity profile, gold has been extensively utilized in various capacities throughout human history. The gold standard emerged as a significant component of monetary policies in the past, however it lost mainstream circulation when production shifted towards fiat currency systems following the cessation of gold-coined circulating currencies in the 1930s and officially ended with the establishment of a fiat currency regime after 1971. According to reports from 2015, approximately 186,700 tonnes of gold is accessible above ground. Present-day global demand focuses mainly on three categories: about 50% in jewelry creation, roughly 40% for investments purposes, and approximately 10% applied in industrial sectors – notably notable due to its malleability, ductility, resilience to corrosion and chemical reactions as well as high conductivity. Owing to gold's unique set of physical properties and distinctive reaction characteristics it continues serving diverse functions; chief among which includes applications in electric connections in all kinds of digital apparatus (considered the most industrial uses of the element) as well as being deployed in the manufacture of colored glasses, decorative metal leafings used in fine arts work, infrared shielding for thermal control purposes. As far back as the ancient periods human medicine also applied gold to alleviate various physical complaints, primarily acting on rheumatic pains using gold complex treatments that include Auranofin, Aurothiomalate, and gold glucoconjugate salts, among other preparations. Due to a peculiarity affecting its valence electrons within the visible range as opposed to many other elements in which plasma oscillations fall into more traditional ranges it shows extraordinary light transmission colors when displayed in thinner sections. Its rarity among metals contributes to high interest in medical use for disease alleviation; notably where the treatment can directly involve either a simple transfer to different ligand binding structures and testing whether this impacts the target biological pathways of specific cancer drugs and various complex formulations containing a stable tetradentate systems
