The Periodic Element Tungsten Overview
Tungsten is a chemical element with the symbol W and atomic number 74. It has an atomic mass of 183.84 u. Tungsten has 74 protons and electrons, and its most common isotope has 110 neutrons. It is located in period 6 and group 6 of the periodic table. Tungsten is a transition metal and is a solid at room temperature. It has a high melting point of 3,422 °C and a boiling point of 5,555 °C. Tungsten has a density of 19.3 g/cm³ and a specific heat capacity of 0.13 J/g·K. It is a nonmetal and has an electronegativity of 2.36.Tungsten is a very important element in many industrial applications due to its high melting point and strength. It is commonly used in the production of filaments for incandescent light bulbs, as well as in the manufacturing of electrical contacts, heating elements, and X-ray tubes. Tungsten is also used in the production of alloys, such as steel, to increase their strength and hardness. Due to its high density, tungsten is also used in the production of weights and counterbalances. Overall, tungsten is a versatile and important element in many industries due to its unique properties.
Everyday objects that contain the periodic element tungsten?
There are many everyday objects that contain chemicals or compounds that can be used to teach chemistry concepts. For example, water is a compound made up of two hydrogen atoms and one oxygen atom, and can be used to teach about chemical formulas and the properties of compounds. Salt, which is made up of sodium and chlorine ions, can be used to teach about ionic bonding and the properties of solutions. Baking soda, which is sodium bicarbonate, can be used to teach about chemical reactions and the properties of acids and bases. Other examples include vinegar, which is acetic acid, and aspirin, which is acetylsalicylic acid. By using everyday objects that contain chemicals, students can learn about chemistry concepts in a simple and relatable way.
Differences in the periodic element tungsten across states of matter
The state of an element can vary greatly depending on its temperature and pressure. At standard temperature and pressure (STP), most elements are either solids or gases. Solids have a fixed shape and volume, while gases have neither. As temperature and pressure increase, some solids can become liquids, which have a fixed volume but take the shape of their container. As temperature and pressure continue to increase, some liquids can become gases, which have neither a fixed shape nor volume. At extremely high temperatures and pressures, some gases can become plasmas, which are highly ionized and conductive. Plasmas are often found in stars and lightning bolts, and have unique properties such as the ability to emit light.
Is the periodic element tungsten dangerous or radioactive?
Tungsten is not considered a dangerous or radioactive element. It is a naturally occurring element with the atomic number 74 and symbol W. Tungsten is a very hard and dense metal that has a high melting point and is commonly used in various industrial applications, such as in the production of filaments for incandescent light bulbs, electrical contacts, and alloys for tools and equipment. While tungsten can be toxic in certain forms, such as tungsten carbide, the pure element itself is not considered hazardous to health or the environment.
Is the periodic element tungsten rare and expensive?
Tungsten is a relatively rare element, but it is not necessarily expensive. It is the 74th most abundant element in the Earth’s crust, and it is commonly found in minerals such as wolframite and scheelite. However, the process of extracting and refining tungsten can be costly due to the high melting point of the metal and the use of specialized equipment. Additionally, tungsten is often used in high-tech applications such as electronics and aerospace, which can drive up the price due to demand. Overall, while tungsten may not be as abundant as some other elements, its cost is largely dependent on market demand and the cost of extraction and refinement.
