The periodic table is the most fascinating and the most useful materials in science. Ever since 1879 Samarium has been apart of the periodic table family it has add another chemical element for scientist to observe. There are over a 100 element in the periodic table that scientists help discover the different types of major minerals. Although there are many element in the periodic table samarium is the few elements that are magnetic. Throught the research essay I will educate you about the element of samarium and more information about the periodic table. Samarium Is a chemical Element with simple Sm with a atomic number 62 and has a atomic mass of 150. Being apart of the Lanthanides series it is a moderately hard silvery metal that oxidises in air. IN 1879 It was founded by By a french chemist Paul Emile Lecoq de Boisbaudran and named after the materials. Also is named after mineral samarskite. Samarium has no major …show more content…
At 20 degrees celsius it is proven that Samarium has stayed a solid. During further testing chemist found 62 protons 88 neutrons and 62 electrons in the element. Based on the evidence founded by the chemist the Element is an Isotope because the protons and electrons are the same. Samarium Is a small light and frizzle item that could be mistaken with brass due to its color and structure. The important role of Samarium is to stimulate metabolism, But can cause is to come times be toxic. Due to the fact that it is toxic It has cause health hazards to be associated with Samarium. Sanarium I the fifth most rare element in the world and can be four times as common as tin. It is impossible to find this product in nature but in contained in many minerals, including monazite, bastnasite and samarskite. Samarium containing ores and are found in USA, China, Brazil, India, Australia and Sri Lanka. At a minimum the produce 700 tons of
Sulfur goes back to the ancient times but it was called brimstone. In 1979, a French chemist named Antoine Lavoisier recognized sulfur was an element and added it to his list of elements. The element sulfur is considered a nonmetal and is the 10th most abundant element in the universe. On the periodic table sulfur is in group sixteen and it is a representative element. Sulfur has an atomic mass of 32.07 with an atomic number of 16. There are three energy levels for sulfur the first energy level is two, the second energy level is eight, and the third energy level is six.
The best-selling novel, The Disappearing Spoon, is written by Sam Kean. The book revolves around the periodic table. It goes into such depth of the table, it is literally an adventure historically, politically, and scientifically. Not to mention, it is relevant to what has been learned this school year, which is what I’ll be talking about in this paper. The book is extremely helpful in learning the periodic table of elements, which is an imperative tool to have when studying physical science or chemistry, for example. It fills an unknown void of what the table is, solving mysteries as the chapter progresses.
Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted
Strontium was discovered by Adair Crawford, an Irish chemist, in 1790 while studying the mineral witherite (BaCO3). When he mixed witherite with hydrochloric acid (HCl), he did not get the results he expected. He assumed that his sample of witherite was contaminated with an unknown mineral, a mineral he named strontianite (SrCO3). Strontium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of a mixture of strontium chloride (SrCl2) and mercuric oxide (HgO). Strontium reacts vigorously with water and quickly tarnishes in air, so it must be stored out of contact with air and water. Due to its extreme reactivity to air, this element always naturally occurs combined with other elements and compounds. Strontium is very
Sulfur is mainly found in the body in amino acids (such as methionine and cysteine) as well as connective
The symbol “As” from the periodic table, belongs to the chemical element Arsenic. Its located in group 15, period 4, and is clasificat as semi-metals. Arsenic’s atomic number is 33, and has a density of 5.776 grams per cubic centimeter. Arsenic melting point is 1090 K (817°C or 1503°F) and the boiling point is 887 K (614°C or 1137°F). The element specific gravities are 1.97 and 5.73, they are respectively to his two solid modifications: yellow, and grey (or metallic). Arsenic’s appearance is steel grey, very brittle, crystalline, and is classified as a semi-metal since it has properties of both.
The fifth element in the periodic table is Boron. Boron was discovered Joseph-Louis Gay-Lussac in 1808. Boron made with boric acid with potassium. The way boron is made today is by heating borax. Boron is a metalloid chemical and has many purpose of use. The symbol for this element is B and its atomic number is 5.
Tyranny has been around for as long as there have been kingdoms, monarchies and democracies. When citizens are voting for whom they want in office, majority of voters would opted out of choosing someone who is a tyrant. When it comes to the famous epic of Sunjata, the tyrant is the villain known as Suso Sumanguru. This villain can be best described as greedy, power hungry, and relentless. The epic focuses though on the life of one of West Africa’s best leaders, Sunjata.
Sam Kean author of The Disappearing Spoon in order to characterize the periodic table as the one of the single most important achievements in human history describes, relates, and emphasizes the importance of the periodic table in the world around us. Depicting his childhood in the introduction, Sam tells the story of Mercury of how a single element connects to history, medicine, and even science. Although the periodic table is around us all the time Sam emphasizes the lack of teaching during his highschool career. Sam even tells the story of how the periodic table was completed and how it was delayed due to the fact of war. These stories and descriptions were implemented to show how a single element arranged in a certain way in the periodic
The Periodic Table is based around the Atomic Theory. Firstly people believed that everything was made up the four elements Earth, Fire, Wind, and Water. This theory evolved into everything being made up of atoms. Breakthroughs throughout history such as the discoveries of the nucleus, protons, neutrons and electrons have pushed this theory forward to where it is today.
This naturally occurring metal element has an atomic number of 80, atomic weight 200.59, melting point of 234.32 K, boiling point of 629.88 K, density at 13.5336 grams per cubic centimeter, with symbol Hg. An element that is found in the earth’s crust and cannot be destroyed or created. This element is called Mercury. Mercury can be traced back to the ancient Chinese and Hindus and has been found in 3500 year old Egyptian tombs. According to Environmental Protection Agency, Mercury can be found in air, water, and soil (2014). Pure mercury is sometimes referred to as quicksilver, which is a liquid metal. Exposure to mercury or its compounds can cause Mercury Poisoning (also known as hydrargyria or mercurialism).
As we mention earlier titanium is 9th most abundant metal in earth’s crust and it is more available in the regions of south Africa and it is available as TiO2(titanium di oxide).
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.
In chemistry, metals compose a great number of the periodic table elements. Each metal has its own characteristic mass,
