Tungsten Periodic Table

The periodic table of elements is a tabular display of the known chemical elements, organized by their atomic number (number of protons in the nucleus), electron configuration, and recurring chemical properties. The elements are listed in order of increasing atomic number (number of protons in the nucleus) and are grouped into rows called periods and columns called groups or families. One of the elements listed in the periodic table is Tungsten, which is denoted by the symbol W and has an atomic number of 74. Tungsten is a hard, dense, gray-white to gray-blue transition metal that is found naturally on Earth only in combination with other elements.

Introduction to Tungsten

Tungsten is a member of the transition metals, which are located in the d-block of the periodic table. The transition metals are characterized by their ability to form ions with different charges, their high melting points, and their ability to catalyze chemical reactions. Tungsten is also a member of the group 6 elements, which include chromium, molybdenum, and seaborgium. These elements are characterized by their similar chemical properties, such as their ability to form compounds with oxygen and their high reactivity with other elements.

Physical Properties of Tungsten

Tungsten has a number of unique physical properties that make it useful for a variety of applications. It has a high melting point of 3422°C, which is the highest of all the elements except for carbon. It also has a high boiling point of 5828°C, which is the highest of all the elements. Tungsten is also extremely dense, with a density of 19.3 g/cm³, which is higher than that of lead. These properties make tungsten ideal for use in high-temperature applications, such as in the production of light bulb filaments and rocket nozzles.

Chemical Properties of Tungsten

Tungsten is a highly reactive element that readily forms compounds with other elements. It is highly electropositive, which means that it readily loses electrons to form positive ions. Tungsten also has a high affinity for oxygen, which makes it highly reactive with air. When exposed to air, tungsten readily forms a thin layer of oxide on its surface, which protects it from further corrosion. Tungsten is also highly reactive with other elements, such as nitrogen, carbon, and silicon, which makes it useful for the production of a variety of compounds, including tungsten carbide and tungsten silicide.

Applications of Tungsten

Tungsten has a number of unique applications that take advantage of its physical and chemical properties. One of the most common applications of tungsten is in the production of light bulb filaments. Tungsten’s high melting point and conductivity make it ideal for use in incandescent light bulbs, where it is heated to produce light. Tungsten is also used in the production of wear-resistant parts, such as cutting tools and abrasives, where its high hardness and density make it ideal for withstanding the high stresses and temperatures involved in these applications.
