What this essay is based on is an interesting element called platinum. Platina del Pinto, which is the scientific name for platinum. It got its name because it resembled silver (Website Title). The atomic number is 78; atomic weight is 195.078; and the abbreviation is PT. The number of neutrons is 117, and electrons is 78. Platinum is a metalloid, which means it’s solid. “Platinum Groups” Julius Caesar Scaliger discovered this metal in 1557. The metal was found in Darién and Mexico. Platinum was used by South Americans; who used it to make artifacts. They combined platinum and gold to make the artifacts last long. The boiling point of platinum is 6,920 Fahrenheit. The melting point is 3,216 Fahrenheit. The oxidation states are +2,+4. The specific gravity is 20 degrees …show more content…
This metal is ductile like most other metals. It can withstand most chemicals but does start to erode away when there is hydrochloric acid and air. Very small amounts of Iridium is added to make it stronger and more resistant. This element is found in mines. It is mined but mixed with other materials like Iridium and gold to make it stronger. The biggest deposit is found in Bushveld, South Africa. The platinum is leached with aqua regia. Then it is heated to a metallic powder. They add pure salt and ammonia to make the material stronger. The most common types are Laurite, Irarsite, osmiridium, cooperite, and Braggite. “Platinum (PT)” The uses of platinum is used for jewelry, catalysts, refractory pellets, and honeycomb structures. It is used in petroleum refining. It is placed on top of aluminum oxide and put into vessels. Rhodium is the most commonly electroplated metal is Rhodium. Petroleum refining use it as a metal for conducting electricity. “Platinum (PT)” The most common compounds are alkyl platinum, olefin polymerization, and polyethylene. Platinum salts are now starting to be used in chemotherapy to cure cancer. The oxidation states are +2,
Dia de los reyes magos is on Jan. 5 - Feb. 2 and the day is about the 3 wisemen, But January the 6th is the special day in Mexico….. this day represents the height of the Christmas season. This celebration is where it is stated that the kings, Melchor, Gaspar, and Balthasar, traveled by night all the way from the farthest confines of the Earth to bring gifts to Jesus, whom they recognized as the Son of God. As well as regal, the Three Kings are depicted as wise men, whose very wisdom is proved by their acknowledgement of Christ's divine status. Arrived from three different directions, the kings followed the light provided by the star of Bethlehem, which reportedly lingered over the manger where the Virgin Mary gave birth for many days. In
Today, it's believed the first coins used and were bronze in West Valley City, around 20017. Coins were employed by Lydia in Asia Minor. The coins of the Lydian were termed "starters" that was a unit of weight. Entrepreneurs were placed having a lion's mind impression and made out of silver and gold metal. Nowadays, as you may think, the coins which can be still outstanding are very useful.
Molybdenum is not found in nature, and the compounds that can be found were, until the late 1700s confused with other elements, such as carbon and lead. In 1778 Carl Wilhelm Scheele discovered that molybdenum was separate from graphite and lead, and was able to isolate the oxide of the metal from molybdenite. Molybdenum was rarely used and stayed in the laboratory until the late 19th century. Plants and animals generally have molybdenum, present in very small amounts.

These include, high strength, low weight, high chemical resistance and high cut resistance. This material does not corrode or rust and is also unaffected when placed in or under water.
Gold is a metal that is dense. Its density can be felt. It is not negligible as some elements appear to be. The element gets melted from solid to a liquid when it reaches a temperature of up to 1066 degrees. This is the melting point of element gold (Saunders, 2003).
Thallium was discovered by Sir William Crookes in 1861, in London. In 1850 Crookes had been given a deposit containing selenium from a sulfuric acid factory in Tilkerode. Crookes extracted the selenium and was left with residues which appeared to contain tellurium. Crookes named thallium after the Greek word ‘thallos’ which means a green shoot or twig, in reference to the unique green spectral line which identifies the element in its emission spectra.
Sodium was founded in 1807 by an English Chemist named Sir Humphrey Davy (Bentor). It was found through the electrolysis of caustic soda (The Element). This means that he found a way to extract sodium from compounds (Newton). First Sir Humphrey Davy would extract a number of active elements and then pa...
Alcohol abuse, psychological abuse,and poverty are some factors that lead Luis Garavito Cubillos to be the world’s worst rapist and serial killer. Cubillos, also known as “the beast” needed to feel god like. He had the worst fantasies but the fantasies were better than real life. He would recreate the murders and soon about 172 young boys became victims of him.
Metalloids can be applied in almost all aspects of life. From being used in gum and toys to technology and spacecraft, metalloids are very useful. For example, Silicon can be used in electrical insulators, fabric softeners, hair sprays, hand creams, furniture, polishes, paints, adhesives, and gum. While Arsenic is used for bronzing, the hardening of lead in shotgun shells, and as a dopant, because metalloids are semiconductive, Antimony could be used in making bells, tools, printing presses, batteries, alloys, bullets, and cable sheathing. Furthermore, Tellurium is used to build electronics and make metals easier to cut. Tellurium is also used in coloring glass, porcelain, enamel, and ceramics. Lastly, Germanium is used in fluorescent lamps, infrared spectroscopes, and infrared detectors. Together, metalloids have many applications that can be used to create and upgrade certain
It is the only gem known to man that is made of a single element.
About 2.8 percent of the earth's crust contains this element making it the sixth most common in the earth's crust. Sodium is found in compounds among dry lake beds, underground, and as well as in seawater in such places as: Belarus, China, France, Germany, India, Russia, Ukraine, United Kingdom, and the United States. Sodium is an extremely chemically active element. If combined with water it tends to react vigorously. For example . Since, sodium is such a dangerous element it has to be handled with care and stored airtight meaning without oxygen. Sodium was first extracted into pure form in 1807 by an English chemist known as Sir Humphry Davy. He used the process of electrolysis where an electrical current is passed through a molten sodium compound such as sodium chloride, sodium was first extracted into its pure form. Many manufacturers today still use electricity to obtain sodium. Sodium is still highly manufactured for many industrial and commercial uses. Sodium has commercial uses as well as industrial uses. From soaps to fertilizers, sodium is used to make water softeners, textiles, and is used as well as to relieve stomach acid, sodium bicarbonate: a white crystalline weakly alkaline salt NaHCO 3 used especially in baking 1 powders, fire extinguishers, and medicine.

The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed.
Metals possess many unique fundamental properties that make them an ideal material for use in a diverse range of applications. Many common place things know today are made from metals; bridges, utensils, vehicles of all modes of transport, contain some form of metal or metallic compound. Properties such as high tensile strength, high fracture toughness, malleability and availability are just some of the many advantages associated with metals. Metals, accompanied by their many compounds and alloys, similar properties, high and low corrosion levels, and affects, whether negative or positive, are a grand force to be reckoned with.
