Although there are many precious metallics, gold holds a special place among many people. This precious metal can be used in many ways, such as the creation and maintenance of art, coins and jewelry. Many times, gold IRA is found hidden in rocks or alluvial deposits.

This metal shines brightly and is dense. However, it is very ductile. It is a beautiful yellow color that shines well and makes an attractive statement. Most of the metal’s characteristics can be preserved because they aren’t affected by humidity or chemicals. Below is a more extensive description of this precious metal:

1. General description. Au is the chemical symbol of gold. Its atomic number, 79, is the chemical symbol for gold. It is classified as a transition metal. Its atomic weight is 196 g.mol-1. It has its unique electronic configuration.

2. Physical description. At room temperature, gold weighs 19.3 grams per cm-3. Gold has high density. There are three temperature reading options that can measure the melting point of gold. This precious metal is not like water. To boil, it must reach a minimum temperature of 2856 degrees Celsius. It fuses and vaporizes at 12.55 KJ mol-1, and 324 KJ mol-1.

3. Atomic description. Every state of oxidation for gold is different. Its electronegativity, according to Pauling scale is approximately 2.5. Its atomic and covalent radiuses are approximately 144, 136, and 166 picometres. The energy released from ionization amounts to around 890kJ.mol-1 (1st), 1980kJ.mol-1 (second).

The word gold actually comes from the Anglo-Saxon word “geolu”, which means “yellow”. “Au”, the chemical symbol of gold, comes from the Latin word “aurum”, meaning gold. The exact moment at which this precious metal was discovered is unknown. Some claim it was 1848 in California. But, gold was extensively used in ancient Egypt and Greece, when the Greeks were first discovered.
