The Elements

symbols that can be related to both groups are the elements. These elements are fire, earth, air, and water. Both the wolf and Billy have connected with these symbolic forces of nature, even though the differences are clear. Humanity is the outcast living…

people regarded water and air as an element. But through Lavoisier discovery, he stated that water and air are compounds. From this, he discovered gases which was decomposed from these mediums. He coined…

Lithium is the chemical element of atomic number 3, a soft silver-white metal. It is the lightest of the alkali metals. The two main parts of every atom are neutrons and protons. The three main subatomic particles that form an atom are protons, neutrons, and electrons. Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center…

Mendeleev’s periodic table was categorizing the elements according to their physical and chemical characteristics with regard to their atomic weights. Mendeleev was the first to come up with a structure for the periodic table with columns and rows. There were other scientists who have worked on tabulating information of the elements even before Mendeleev, however, he was the first scientist to come up with a periodic trend to predict the properties of elements which were not discovered at that…

Table. Just for example, the modern periodic table arranges elements in order of increasing atomic number. Mendeleev’s ordered them based upon increasing atomic weight. Another difference is that the modern periodic table has some elements that Mendeleev had not found. One of these family of elements are the non-reactive noble gases. There are also no gaps in the current Periodic Table. In Mendeleev’s version, he had gaps where elements had not been found yet. The last difference is that the…

The element name given is Phosphorus, it is symbolized in on the periodic table as a P. Its atomic number is 15 and the atomic mass is 30.974 (which is a rounded number). Group number the element is apart of on the periodic table is 15. Phosphorus’ listed isotopes are P-31 (stable) and 23 others and its electron configuration is [Ne]3s2 3p2. Physical properties of the element are varied depending on which allotrope of the element you are talking about. White Phosphorus has a melting point of…

It is an element. It is rare. It is Hassium. Out of a total of 118 elements on the Periodic Table of Elements, Hassium is just one. Hassium is the 108th element on the periodic table. Have you ever heard of Hassium? The term Hassium was derived from a german state of Hesse, where Hassium was first made. Hassium was discovered in 1984 by Peter Armbruster and Gottfried Munzenburg. These two inventors developed this element in Darmstadt, Germany which is located in Europe. Hassium has a…

Disappearing Spoon Essay Tanner Rapp In this book about the periodic table and how each element was discovered and how it affected each scientist when they discovered it. The story shows scientist such as Maria Goeppert, Dimitri Mendeleev, Robert Bunsen, Fritz Harbor, William Crookes, and many more. However, in this essay I am going to write about Dimitri Mendeleev, Robert Bunsen, and Fritz Haber. Dimitri Mendeleev is a very important scientist when it come to the periodic table, he is…

Cast Iron is processed to remove impurities or slag and is turned into a steel alloy. Therefore steel is an alloy and Iron is an element. Steel is also called as an alloy of iron, with the content of carbon controlled. 4% of carbon in Iron makes it Cast Iron and when the carbon content is less than 2%, the product is steel. Cast Iron is made from pig iron, which is the by-product of…

Magazine, Mental Floss, Slate, The Believer, Air & Space, Science, and The New Scientist, has created a user-friendly book about how to explain the periodic table and the elements that occupy it by writing the book The Disappearing Spoon: And Other True Tales of Madness, Love and the History of the World From the Periodic Table of Elements. He provides an insight into the world of chemistry that relates to his audience, even those who do not have a PhD in a science field. As the book goes on,…
