A Brief Description of Gold

Gold is a chemical element with the symbol Au and atomic number 79. It is a bright orange-yellow metal that is soft and malleable. It is in the group of transition metals. It is also a group 11 element. Here is a brief description of gold. For more information, see a video about the chemical properties of gold. This is the most common chemical element in jewelry. It is a relatively rare metal, so it is very valuable in jewelry and is considered an investment.


Although gold is not a primary element in jewelry, its high conductivity makes it useful for many industrial applications. It is especially important in microelectrical circuits. It also helps shield electronic devices from the passage of infrared radiation. Its low cost and high corrosion resistance also make it popular for bearings in corrosive atmospheres. Despite its industrial uses, gold is also widely used in arts and crafts. It is safe to handle and is considered environmentally friendly.

Since gold is a good reflector of electromagnetic radiation, it is commonly used in aerospace and defense applications. It is also used in infrared protective faceplates in thermal suits and astronauts’ helmets. Even high-quality CDs are made with a thin layer of gold. However, gold ion concentrations may be low, so it is important to avoid overdoing it. In addition, some gold compounds exhibit aurophilic bonding. This describes the tendency of gold ions to interact with one another at a distance that is much greater than the conventional Au-Au bond. The distances between two ions are similar to those of hydrogen bonds.

The concentrations of gold in oceans vary significantly. Some ocean samples contain more gold than others. In general, samples taken from the south Atlantic and central Pacific are similar in concentration, but Mediterranean samples are higher. The higher concentrations are thought to be the result of winds, rivers, and other sources of dust. It is an excellent conductor of heat and electricity, but is soft and brittle. For this reason, it is often alloyed with other metals to create alloys that will increase its hardness and color.

The concentration of gold in the ocean is very low. In contrast to other commodities, it does not exhibit a supply-and-demand relationship. When the price of another commodity rises, so do gold prices. This is due to the fact that gold is a non-conducting metal and therefore, the more it reacts with the environment, the more it attracts the attention of other people. This is because it catches fire. And this can occur in the ocean.

Because of its inherent value, gold is prized and often used as decoration. Throughout history, humans have been rewarded with gold for their greatest achievements. Despite its popularity as a decorative material, however, it is still a precious metal that is not prone to melting or losing its lustre. The colour of the metal is important when it comes to jewelry, because it affects the value of a piece of jewellery. It is one of the most popular choices among jewelry makers in the US.
