Chromium is part of the periodic table this element has the atomic number of 24 which means that it has 24 protons and 24 electrons. Its atomic mass is 51.996, but when reduced it will be 52. The density of the element is 7.19, and the temperature for it is 20 Celsius. And the melting point of the element is going to be 1907 Celsius. This information gives you the idea of what my element has. The history of the element is very interesting, because it came from a Greek word. But it was discovered
In the Lithic Ages, people used a variety of techniques to achieve sharp edges from stone. From the Lithic Ages, humans transitioned to the Copper and then the Bronze Age. These periods are defined by the advent of extracting and processing soft metals such as copper, tin and their alloy bronze to make new tools. Copper and bronze are easy to work and will produce more durable tools that can take more of a beating than stone tools. There was a trade off when converting from stone tools to bronze
There are four major grades of stainless steel manufactured for various applications. The most commonly used stainless steel in any home or business is 316 Stainless Steel Plates for utilization in different industries today. This subcategory for 300-grade steel means that the level of chromium in the overall steel composition is higher making it more resistant to corrosion without the use of other organic sealants. The high degree of chromium mixed with oxygen gives stainless steel the natural barrier

protons. Its mass number is 63.55. It is a transition metal in the middle of the periodic table. The symbol for copper is "Cu", which comes from the Latin word cuprum, which came from the Latin word for the island of Cyprus, where copper was found. Copper can be found as a metal in the ground. It is found in small amounts in living things. Some mollusks and arthropods have blue blood because they have copper in their blood. Copper may be the oldest metal in use, as ancient copper tools have been found
was already known for a long time during the Egyptian, Greeks, and Chinese civilizations. But identifying this chemical as an element such as the atomic number and the atomic mass, were discovered by Albert Magnus. The appearance of arsenic is semi-metal and has a silver-grayish color. Arsenic were used
main competition: American National Can, Continental Can, Reynolds Metal and Ball Corporation. Van Dorn Company and Heekin Can were regional threats. CCS and their main competitors comprised 61 % of the market in the metal can industry. There were approximately 100 other firms that served the rest of the market, but they were not plausible threats. Competition between the large firms was intense. Ball Corporation and Reynolds Metal were known
Latin. Metal Chelation is a process when a polyvalent metal ion form covalent bonds with a drug and binds tightly to form a 5 or 6 membered ring. 5 and 6 membered ring structure are very stable because their bond angle has no ring strain. Thus, when a compound is chelated, it will not be able to pass through the biological membrane, in another words, it will not be metabolise by the body but to be pass through the renal without being absorbed and being excreted though urine. Essential metal such as
Metal and architecture has evolved over centuries, with successive eras opening up new technical and elegant possibilities through the development of different types of metals. Metals are dense, lustrous materials that are highly conductive of heat and electricity. Some facts about metals are that they are generally ductile, meaning that they can be hammered thin or drawn into wires. Metals can also be liquified by heating and then resolidified by cooling. Presently metals are the strongest building
