Gold – The Most In-Demand, Precious Metal

While many precious metals are available for public consumption today, many still hold a special place within the hearts of many. This precious metal is used for many purposes including in the creation art, making coins and jewellery. The gold ira can be found in both alluvial and rocks-hidden grains. This particular metal has a bright, shiny appearance and is very dense. It is also extremely ductile. It shines beautifully and has a bright yellow color.

The metal’s natural characteristics are well preserved, as they don’t get affected by chemicals or humidity. Here is an even more detailed description of this precious material:

1. General description. The chemical symbol that represents gold is Au. Its atomic numeric number is 79. It is classified in the category of a transitional metal. Its average weight is 196g.mol-1. It also has a unique electronic configuration.

2. Physical description. Gold is a dense metal and at room temperature weighs about 19.3 You can determine its melting point by using three different temperature readings. This precious metal has a high boiling temperature, which is higher than water. It fuses at 12.55kJ/mol-1 and 324kJ/mol-1.

3. Atomic description. Each state of oxidation is unique to gold. On the Pauling scale, it has an electronegativity of 2.5. Its atomic-, covalent-, and Van de Waals radius is approximately 144, 136, and 166 picometres. The amount of energy released by ionization is about 890 kJ.mol-1 (1st), 80 kJ.mol-1 (2).

Gold is actually a term that comes from ‘geolu,’ an Anglo-Saxon word giving the meaning of yellow’. The Latin word aurum’, which means gold, is used as the chemical symbol for gold.
