These types of gold are made by mixing other metals such as silver, copper or zinc with pure 24 carat gold. The three main colours of gold: Yellow, (rose gold) Pink Gold and White Gold. Gold also offers durability and shine that no other material can match! From delicate pieces like necklaces or earrings to chains bracelets and pendants, gold is an excellent choice because of its versatility in the design along with how long-lasting they are against wear-and-tear from everyday activities. Gold has always been a favourite metal for making fine gold jewellery, but it's not just about the colour. We use fine 18ct solid gold to make our Fine Jewellery for women. Gold shares qualities with other precious metals like silver, platinum, or palladium they don't rust or corrode either! (But not all precious metals are noble metals) We use 18ct Solid Gold to Make Our Jewellery Not only does gold has an attractive colour, but also has many qualities that make it desirable like durability to corrosion and oxidation which makes it a noble metal. ![]() Gold is one of the most sought-after metals in the world and there's no wonder why. Hence why Scientific Chemical Symbol for Gold is Au because its Atomic Number (a number that represents the number of protons in an atom) is 79. The reason why Chemical Symbol for gold 79 is because if gold was to be placed under a microscope, we would see electrons orbiting around a nucleus that contains 79 protons. Why is Atomic Chemical Symbol for Gold 79? Gold is a good conductor of electricity so it can be used for connectors on instruments with electric circuitry as well. Gold is not just used to make coins, gold bars, and jewellery but can also be used to coat electrical devices in order to prevent corrosion. Gold being soft allows you to make gold jewellery, by mixing other metals such as silver or copper to make what are called 'gold alloys'. But it is usually mixed with other metals because pure gold is too soft to work easily. The red-orange metal can be found in nature as nuggets or grains. It is a chemical element of the group of elements known as transition metals. ![]() Gold is a dense, soft, shiny solid metal. The name is from the Latin: aurum, meaning "shiny dawn". The high density and weight of gold is the reason that it also belongs to the group of heavy metals.Gold is a chemical element with the symbol Au and atomic number 79. In comparison plutonium is not much heavier with 19.74 g/cm³. The density amounts to an incredible 19.3 g/cm³ (at 20 degrees Celsius). One remarkable physical property is also its high density and the accompanying high weight. Which makes it, along with copper and caesium, one of the most extremely rare metals to boast a real colour. One of the most notable properties of gold is surely its bright yellow colouring and particular lustre. It is only possible to damage and dissolve gold using so-called “king’s water” (three parts concentrated hydrochloric acid and a part nitric acid). ![]() Also food acids do not affect gold teeth. Therefore in dental medicine dental fillings are often made of gold, because gold fillings are not attacked from acids in the mouth and in food. Electronic components manufactured using gold are extremely robust against environmental influences and therefore remain conductive for very long periods. The high corrosive resistance makes gold for example interesting in the manufacture of electronic control systems for high-end electrical equipment. For example gold exhibits no reaction to air and water and also does not itself corrode when exposed to long periods of harsh weathering conditions. Gold is also termed to be chemically “inert” hence, it reacts very sluggishly when reacting to other substances. What makes this precious metal interesting for industrial and medical uses is its high corrosion resistance. Therefore in nature, only one isotope exists, always possessing the same number of protons and neutrons in the atomic nucleus. Furthermore, gold as well as for example Plutonium and Caesium belong to the so-called “ pure elements”. As all the other chemical elements with the numbers 21 to 30, 39 to 48, 57 to 80 and 89 to 112, gold also belongs to the so-called “transition elements” also known as “ transition metals”, because all the elements with these atomic numbers are firstly metals and secondly exhibit an increasing number of electrons in their electron shells. ![]() In the periodic table gold has the atomic number 79 in group 11. From its name the chemical symbol “Au” for gold is derived.
