Copper comes from a Latin term cyprium (after the island of Cyprus) meaning “the metal of Cyprus.” Copper dates back to prehistoric times but has been mined for 5000 years, however it’s exact discoverer is unknown. Cu is Copper’s chemical symbol. It contains 29 protons/electrons (atomic number) and 35 neutrons. It’s atomic weight is 65.39….

The chemical component K is a soft, light, silver white metal. It is a member of the alkali metals, a group ( IA of the periodic tabular array ) with similar physical and chemical belongingss. Its chemical symbol is K ( from kalium, the Latinized version of the Arabic word for “ alkali ” )…

Lead is a lustrous, silverymetal that tarnishes in the presence of air and becomes a dull bluishgray. Soft and flexible, it has a low melting point (327 C). Its chemicalsymbol, Pb, is from plumbum, the Latin word for waterworks, because oflead’s extensive use in ancient water pipes. Itsatomic number is 82; itsatomic weight is 207.19….

Magnesium is the 12th component on the periodic tabular array. It is located in the 2nd group called the alkaline Earth metals. Natural Mg contains three different isotopes, and there are 12 others that are recognized. Seawater is a rich beginning of Mg in the signifier of salt. Magnesium is the 8th most abundant component…

Mild SteelIntroduction:Steel is not a single alloy rather it a generic name for iron based alloys or an alloy which has Iron (Fe) as the major component. Based on the alloying elements in iron we have different classes of steel. For example Fe with 12 or more wt% of chromium (Cr) is stainless steel, which…

Finding the percentage of copper in brass alloy. Introduction This is an investigation to find out how much copper is in a brass alloy. The brass alloy we are experimenting on is called Muntz Metal. Muntz metal is 60% copper, 40% zinc and a hint of copper. Muntz metal was developed as an alternative to…

The Reverend William Gregor in 1791, who was interested in minerals, discovered titanium. He recognized the presence of a new element, now known as titanium, in menachanite, a mineral named after Menaccan in Cornwall (England). Several years later, the element was rediscovered in the ore rutile by a German chemist, Klaproth. The pure elemental metal…

The use of plastic in injection molding has facilitated the creation of various products. This manufacturing process incorporates a mold, clamping component, injection unit, and different types of plastics. Throughout its development, injection molding has introduced new techniques and products to improve the production of molded parts. Injection molding is a versatile manufacturing process that…

Vanadium is a really interesting and utile component. It is solid at room temperature and in its pure province it is a grey silvery metal. It is soft and malleable and it has good corrosion opposition to alkalis sulfuric acid  hydrochloric acid. and salt Waters. Its element symbol is V and its atomic figure is…

The engine is the single most important part of the automobile. Without it, the car simply will not move. It is important that the cylinder or engine block is built to withstand the high temperatures and pressures that are put into it and it is equally important that the engine block is built to last….
