A pure substance can be classified as an element or a compound. An element contains only one kind of atom, and it cannot be transformed into a new substance by any chemical or physical means. Most metals, non-metals, and metalloids are elements. A compound can also be a pure substance i...
Alloys and solutions may or may not be pure, depending on who you ask. On the one hand, alloys like steel, brass, and bronze have a set composition. On the other hand, if you examine these metals closely, they have different phases and structures within them. Usually, a solution of sa...
It has been one of the most commonly used metals since antiquity after the Bronze Age ended in approximately 1200 BCE. Pure iron is a soft, ductile metal that is susceptible to rusting when exposed to air. Iron is often alloyed with carbon and other elements to increase its hardness, ...
Metals occur naturally on earth, but when we give this a deeper thought, metals are found below the earth, hidden in special rocks which are called ores. Metals such as iron, copper, and tin have to be extracted from their ores. Generally, pure metals are weak in structure, they cannot ...
During electrolysis, a current is passed through the metal to separate pure metals from impurities. The process of zone refining utilizes the crystallization of metals to ensure that only pure metals are left behind. Because impurities in metals such as silicon do not crystallize, they turn into ...
Physical Material Properties of Metals The physical properties of metals are: Luster The property of metals which in the pure state usually shines. The shine on the metallicsurfaceis the metallic luster. They shine in light due to the reason that the metals possess free electrons that vibrates ...
The physical property of malleability is a property reserved for metals only. Some of the most malleable pure metals are gold, silver, aluminum, and copper. Pure gold is so malleable that it will dent or change shape simply by being dropped. Pure gold is so malleable that it is difficult ...
Gold has been called the most beautiful of all chemical elements. Its beauty has made it desirable for use in jewelry, coins, and artwork for thousands of years. It was one of the first pure metals to be used by humans. Gold is one of the few elements that can affect politics and ...
While bronze mostly contains copper (87-88%) and tin (12-12.5%), other materials are often added to create a range of alloys with different properties. These materials could be metals (such as aluminum, manganese, or zinc) as well as nonmetals or metalloids (such as phosphorus or arsenic...
