    down into five individual branches. Analytical chemistry attempts to determine the exact chemical compositions of substances through the measuring the physical and chemical properties of matter. Physical chemistry is the combination of chemistry and physics analysing the physical make up of chemical properties and the interactions between energy and matter. Organic chemistry, is heavily based on the element of carbon and its relation with life. Due to carbon’s complex and unique properties…

  • Fundamental Features Of Atom Research Paper

    A atom is the basic unit of an element .it is a form of matter which cannot be broken down any further .an atom consist of sub atomic particles which are protons, neutrons and electrons .I will be looking at specifically the atom lead. Every element in the Periodic Table has been given a letter symbol , the symbol for lead is Pb.i will now describe the sub atomic particle in lead .protons are in the nucleus of the atom , All atoms of the same element have the same number of protons. This number…

  • PZT Case Study

    4.2.1. Material: Lead zirconate titanate (PZT) PZT is a short for lead zirconate titanate inorganic compound that has a chemical formula of Pb [ZrxTi1-x] O3 (0 ≤ x ≤ 1). PZT is made and composed of the two chemical elements lead and zirconium combined with the chemical compound titanate while formed under extremely high temperatures. The dielectric constant of PZT can range from 300 to 3850, depending upon orientation and doping. PZT possesses piezoelectric effect meaning that it changes shape…

  • Copper Atom Research Paper

    Atoms are what make up what we call “matter.” They are the smallest units of a chemical element, and they consist of protons, neutrons, and electrons. These components form an atom’s subatomic particles. Before discussing the copper atom at length, we must first be able to understand the components that comprise an atom. The first of these components that make up an atom is the proton. The proton is a very important part of an atom, because the atomic number of an atom is equivalent to the…

  • Difference Between Crystalline And Amorphous Solids

    Crystalline and Amorphous Solids  Solids can be divided into two classes: crystalline and amorphous. Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures. Crystalline solids, or crystals, have distinctive internal structures…

  • Chemistry As A Periodic Table

    as if the bright colors on the chart were generating warmth (energy) and that chart was an exhibit of the Periodic Table. For years, different people ventured to group elements by their chemical traits. However, Dmitri Ivanovich Mendeleyev (1834-1907) a Russian chemist is first to devise a periodic table of elements.…

  • Alchemists Chemical Reaction

    regular metals, such as copper, into gold. However, they were not aware at the time that copper and gold were two different atomic elements and instead believed them to be compounds. Thinking these metals could be changed chemically or physically in labs, alchemists pursued this dream to no advantage. Although it is not possible to change ordinary metals to gold through chemical reactions, physical reactions, radioactive decay, or nuclear fission, it is possible to change them through nuclear…

  • The Theory Of The Cubical Atom: The Lewis Dot Structures

    Gilbert Lewis first introduced his theoretical dot structures in 1916. Today, these same dot structures are used to illustrate the chemical bonding nature of atoms. How did Lewis formulate these brilliantly simple representations of nature? The Lewis Dot Structures we know today actually derive their functionality from Lewis’ own model of the atom, the Theory of the Cubical Atom. This essay will explore the functionality of Lewis’ cubical atom and how this model led to the Lewis Dot Structures.…

  • Scandium Research Paper

    How are elements useful for a particular use? An element is made from one type of atom and this article is about the element Scandium. Scandium was discovered in the year 1879 by Scientist Lars Fredrik Nilson in the university of Uppsala. The origin of the name comes from the word Scandia, which is the latin name for Scandinavia. This element belongs to group 3 which consists of transition metals and Scandium shares this group with the element Yttrium. There are 4 groups in the periodic table…
