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. Boron is an important element it is used as a nutarian for plants. The weight if boron is 10.81 and has a density 2.37 grams. Boron has a melting point of 3,767 and a boiling point of 7, 232. This is the second hardest element after carbon. Boron is an element that has been around for a while boron is Arabic for white. Boron is an element that is resistant to heat. And ha another form called crystalline form and that is when
it is its hardest. While boron is in its crystal form it is not reactive but when it’s in normal form it is reactive. Born is known for controlling nuclear reactions, it absorbs the reaction. Boron is rare on other planets but it occurs on the earth’s crust. Boron is almost impossible to make because of carbon. But when carbon and boron are together it is super hard and heat resistant. Since boron is from plant cells it occurs in almost all foods that are from plants. Boron is used for many things and is indeed a hard element. It is also very heat resistant considering its melting point. Born has been used for many years and is made by heating borax today. Boron has two forms and is reactive in one form and is unreactive in another form.
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
Born in Gotha, Germany in 1752, Blumenbach went on to Jena to study medicine. He completed his doctoral training at Gottingen in 1775. Just a year later, he was appointed as an extraordinary professor of medicine. His study of the history of man showing the value of using comparative anatomy and his classification of the five varieties of man were two important contributions made by Blumenbach (1911 Edition). He wasted no time in becoming one of the most influential members of the fields of comparative anatomy, zoology, physiology, anthropology, and craniology, in fact, Blumenbach is considered to be the founder of anthropology as well as craniology. In his construction of this new field of physical anthropology, he used the methods of natural historians, and applied those methods to the human species (Keith 106). Objectifying the study of mankind, Blumenbach collected numerous specimens from various races. Skulls, skin, hair and pictures were among the items collected. From each item, the location, as well as race of the item, was known and recorded. Prior to Blumenbach's systematized assortment of specimens, the only collections "consisted of miscellaneous oddities preserved in the 'cabinets' of noble houses, for the idle amusement of the curious." (Keith, 106). Blumenbach' s more complete collection allowed intensive study into the racial history of mankind, which is just what he wanted to do. Blumenbach was also the first to study the actual form of skulls (Retzius 283).
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
Two chemists came upon the discovery and those two are: Sir William Ramsay, who is from Scotland, and Morris M. Travers who is from our homeland. This element was founded on May 30, 1898. The way that those two came upon the element Krypton was that they first found the elements Argon and Helium. From using their common knowledge they figured that there had to be some elements between those two on the periodic table, so they did a ton of experiments and through trials and trials they came up with a couple more elements and one of those elements was Krypton. Next the essay will discuss the shape of Krypton and where it is found.
The Beryllium element, an alkaline earth metal which belongs to group II of the periodic table, was first discovered in 1798 by L.M. Vauquelin. Vauquelin,a French chemist, was doing work with aluminum and noticed a white powder that was nothing like that of aluminum or any of its derivatives. Vauquelin named this mystery powder, gluinium because of its sweet taste was like that of glucose. In 1828, Wohler, a German metallurgist reduced it to its metallic form and renamed it beryllium.(figure 2)
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.
Discovered in 1808 by J.L. Gay-Lussac and L.J. Thenard in Paris, France, and Sir Humphry Davy in London, England, boron is element number five on the Periodic Table of the Elements. The name "boron" comes from the Arabic "buraq" (pronounced borax). The actual element boron is not commonly used, but compounds of boron are very common. These compounds can be found in such household items as detergent. Boron is also used in Pyrex glass, which makes the glass more heat resistant. Boron is also an essential mineral for plants and animals, although it can be toxic in large quantities (Chemsoc 1). Boron has many common uses, but there are also many advantages to using it as and alternative form of fuel.
Rudolf Karl Bultmann (1884-1976). Rudolf Karl Bultmann (1884-1976) was born on August 20th, 1884. Wiefelstede, in what was then known as the grand duchy of Oldenburg. His father, Arthur Bultmann, was an Evangelical-Lutheran pastor, his paternal grandfather, a missionary to Africa, and his maternal.
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.
The modern periodic table is very much like a later table by Meyer, but arranged, by Mendeleev’s, but it had to be according to the size of the atomic weight. The only thing though that was made by Mendeleev’s was Group 0, which was then added by Ramsay.
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.
This bluish-white element is classified as a heavy metal, due to its metallic physical properties such as a metallic lustre, a high density of 11.342 grams per cubic centimeter, and a low melting
In the periodic table Beryllium is the first element in the second group. The chemical symbol is Be. Beryllium is an Alkaline earth-metal which means that Beryllium is really reactive but not as reactive as the Alkaline metals which is the first group. Beryllium has a melting point of 1287 degrees celsius and a boiling point of 2468 degrees celsius. In 1797 Nicholas Louis Vauquelin founded Beryllium. The density of Beryllium is 1.85. Beryllium is between Lithium and Boron. Beryllium is a shiny,steel gray,and metal that can be used for missiles, high-speed aircraft,spacecraft, and communication satellites. When used as an alloying agent in Beryllium copper beryllium can be used as a spring or a spot-welding electrode and non-sparking tool.

Dalton was the first person to develop a scientific atom theory, the ancient Greeks had ideas about the atom but could not prove it scientifically. Antoine Lavoisier and Dalton are responsible for the discovery of 90 natural elements. Dalton also explained the variations of water vapor in the atmosphere, the basis of meteorology. Dalton’s atomic theory says that each element contains its own number of atoms. Each element has its own size and weight.
