Elements Of The Periodic Table Essay

575 words - 2 pages

Elements of the Periodic TableElementsThe two elements that will be discussed are Iron (FE) and Potassium (K). The paper will discuss the periodic nature and properties of each of these elements, where each are categorized on the periodic table and how each is classified. The importance of each of these elements in nature and its use. Any drawbacks with the elements will also be discussed.Periodic Nature and PropertiesThe first element is Iron (Fe) its atomic number is 26, it is silver in color, a lustrous metal and is a very magnetic solid. Iron is very strong and malleable. It has a very high melting point of 2800 °F and a boiling point of 5182 °F. (Winter, 1993-2012) The atomic mass of Iron is 55.87 and has a density of 7.87g/cc. It is in the transition metal category of the periodic table. Iron has very high oxidation properties and when exposed to air will react with the oxygen and form rust.The second chemical element that will be discussed is potassium (K). Potassium's atomic number is 19, its atomic weight is 39.0983. It has a boiling point of 146.08 °F, a melting point of 1398 °F and a density of856 kg m-3. (Winter, Web Elements, 1993-2012) Potassium like iron is a silvery white color and is in the alkali metal group on the periodic table and oxidizes very quickly. It is very reactive and the least dense known metal.Importance in NatureIron is found in nature and is rather abundant and is formed in the Earth's crust. It is used to create other metals that are used for building, iron ore, steel, wrought iron and cast iron. Iron also has an important role in the human body and biology. It will combine with molecular oxygen in hemoglobin and myoglobin. Iron also aids in the oxidation...

At that time protons, neutrons, and electrons were not discovered yet. His table led to the periodic law which states that elements are arranged in order of increasing atomic mass, and show a periodic repetition of properties. mendeléev concluded two things: if an element did not match elements

Development of the periodic table

710 words - 3 pages Essay - The Development of the Modern Periodic Table Rosie PurchaseIn 1817, a German scientist called Johann Dobreiner published his idea, the law of triads. These triads were an early attempt of organising the chemical elements. Each triad was a group of three elements that were specifically placed together due to their similar properties, appearance and reactions. He created 6 triads, of which some examples are: lithium, sodium and potassium

However, the major physical property of the transition metals is, besides copper, the transition metals are white shiny metals. They are also well known for having a high melting point, and a high

A Brief History of the Periodic Table

836 words - 3 pages Virtually all science classrooms will have at least one common thing posted on their walls; a poster of the periodic table. The periodic table is simply a chart of all known elements, arranging them as defined by periodic law; it orders the elements by increasing atomic number, displaying the periodicity of chemical and physical properties in the elements. The first contributions to the periodic table were made in antiquity, with the discovery
