Authors; Authors and affiliations; J. C. Yannopoulos; Chapter. It makes sense to kick off with the most familiar of the three: Gold. Lithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure.The chemical symbol for Lithium is Li. Physical and Chemical Properties of Gold. It is a good conductor of heat and electricity. Being ductile means that it can be dawn in to thin wires. The Latin name for gold is “aurum”. Under standard conditions, it is the lightest metal and the lightest solid element. It belongs to group 11, periodic number 6 of the periodic table and has the atomic number 79. Gold has been synonymous with wealth and riches throughout human civilisation, and was likely the first elemental metal known to man, due to its low chemical reactivity meaning it can be found naturally uncombined with other elements. Gold is an attractive and highly valued metal that has been in use for thousands of years. It is a soft, silvery-white alkali metal. When mixed with other chemical impurities, gold can take on tinges of green, red, black and red. Gold is a soft yellow metal, with the highest ductility and malleability of any metal. Chemical and physical properties. Chemical Properties Physical Properties Mechanical Properties Thermal Properties Applications. Gold’s unique properties and versatility make the metal indispensable in engineering and electronics, and its application as a nanomaterial is offering new solutions to a range of global health and environmental challenges.. Below are some of these unique properties of gold: Gold is the most malleable of all metals and soft enough to be cut with a knife. As with most metals, gold is both ductile and malleable. From its name the chemical symbol “Au” for gold is derived. Though King Tutankhamun was a minor Pharaoh and died aged 18, his coffin alone contained 112 kg of gold. Basic Chemical Properties of Gold “Au” is the chemical symbol for gold. In principle gold is a chemical element. Gold chemical properties define its chemical formula, isotopes, oxides, electronegativity 2 Citations; 611 Downloads; Abstract. Stone age peoples hammered gold into plates for ornamental purposes. Really quite large amounts were gathered together. Introduction. Gold. The distinctive yellow hue of gold is most obvious when the gold is pure. Gold - Gold - Properties, occurrences, and uses: Gold is one of the densest of all metals. Gold is the material of choice to guarantee reliability of performance. In the periodic table gold has the atomic number 79 in group 11. It is also soft and the most malleable and ductile of the elements; an ounce (28 grams) can be beaten out to 187 square feet (about 17 square metres) in extremely thin sheets called gold leaf. Like all alkali metals, lithium is highly reactive and flammable, and is stored in mineral oil. Gold is a chemical element with Au as its symbol.
