What is gold?
Gold has long been known as a symbol of wealth, power and beauty and is used as a valuable resource all over the world. Also, gold is considered as a fixed capital and value holder in the face of economic changes. Gold (Au) is a metallic element with a shiny yellow color. The characteristics of this metallic element are high malleability, beauty, unique luster, high resistance to environmental factors such as weather and temperature changes. The plasticity of gold is a setting that can be made from one gram of pure gold into a sheet measuring 1 meter by 1 meter. Gold can be thin enough to let light pass through it, and you can even create a shape on pure gold with a nail. Because of this soft property, in various uses, by adding some other metals, they increase the resistance of gold, which causes a change in the color of gold. Gold has a good resistance to air and moisture and is very stable in acids. The only acid that can dissolve gold is known as Tizab Soltani (nitro-hydrochloric acid). Gold hardly undergoes chemical reactions. /p>
Uses of gold
The applications of gold metal in various industries are very wide and diverse, from jewelry and electronics to medicine and space industries. Below are some of these uses: Jewellery: Gold is used as one of the most expensive and popular materials in the jewelry industry. It is used to make rings, earrings, chains and other ornaments, which are very valuable because of the luster and beauty of gold. Electronics: This metal is used for electrical connections in mobile phones, computers, televisions and other electronic devices. It is also used in the production of sensors, chips and other electronic components.
Medicine: Gold is used in the medical industry as an antiseptic and corrosion-resistant material. It is used in the production of surgical instruments, implants and medical devices. Space: In space industries, it is used as a protective coating for space equipment such as sensors, cameras and electrodes. These covers protect against temperature changes and harsh space conditions. Other industries: Rose metal is also used in other industries such as the automotive industry, military industry, production of communication tools (such as antennas) and home appliance industries.
Features and properties
With its characteristics and properties, gold metal has become one of the multi-purpose and valuable materials in various industries and has a unique importance in human life. Chemical properties: Gold is a chemical element with Au symbol and atomic number 79. This rare and non-metallic metal is not usually found in pure form in nature and mostly exists as compounds with other metals. Physical properties: Gold is a soft, flexible and malleable metal that is golden yellow in its pure state. It also has a high melting point and unique electrical and thermal properties.
Mechanical properties: Gold has a high resistance to flexibility and deformation, which makes it one of the popular gems for use in jewelry. This metal also has a good resistance to corrosion and rust, which makes it suitable for use in different environments. Electrical properties: This metal is one of the best materials for conducting electricity, which is used to produce electronic components and devices. It also has high reflective and absorbing properties for light, which is used in jewelry and artistic products. Healthy properties: Gold is known as an antibacterial substance that is used in the medical industry to produce medical tools and devices. The use of gold in the restoration of teeth and the production of antibacterial sprays are also among its health properties.
A look at the future of gold
Forecasting the price of gold in the future is affected by several factors, which include the following: Economic factors: such as inflation, dollar rate, the state of the labor market and domestic production that can affect the price of gold. Political factors: The international system, sanctions and political relations with other countries that can lead to changes in the price of gold. Global factors: Such as the economic situation of the world, changes in the capital market, environmental situation and climate changes that may affect the price of gold. Due to these factors, it is difficult to accurately predict the price of gold in the future, but analysts and experts continuously provide analyzes in this field that can help make better decisions for investing in the gold market. /p>
