  • Silicon And Oxygen Minerals
    300 words
    A mineral is a natural inorganic solid wit a set atomic structure. Each mineral has a set chemical composition and specific physical properties. There are over 300 minerals today the earth scientist has discovered. There have been 3000 minerals that have been categorized into the following categories, which I will describe to you in the next paragraphs. There are 7 different categories that it is broken down into. The first one in. To be in these categories you must have silicon and oxygen miner...
  • Highly Specific Reaction Between Two Compounds
    1,522 words
    ... dress of atoms in them are quite feasible. Larger atomically precise structures with complex three-dimensional shapes can be viewed as a connected sequence of small atomically precise structures. While chemists have the ability to precisely sculpt small collections of atoms there is currently no ability to extend this capability in a general way to structures of larger size. An obvious structure of considerable scientific and economic interest is the computer. The ability to manufacture a co...
  • Theory Of Atoms In Molecules
    462 words
    The molecular structure hypothesis - that a molecule is a collection of atoms linked by a network of bonds - was forged in the crucible of nineteenth century experimental chemistry. It has continued to serve as the principal means of ordering and classifying the observations of chemistry. The difficulty with this hypothesis was that it was not related directly to quantum mechanics, the physics which governs the motions of the nuclei and electrons that make up the atoms and the bonds. Indeed ther...
  • Crystal Lattice Structure
    308 words
    web. The atoms in a crystal are in a regular repeating pattern called the crystal lattice... A crystal lattice is defined by a repeated three-dimensional unit... The basic building block of these crystalline structures is known as the "unit cell" and this "unit cell" repeats itself over and over to form a lattice... When a pure metal starts to form from a cooling molten state, the atoms arrange themselves in an ordered geometrical pattern that is repeated over and over again producing a crystall...
  • Atom Supplies One Electron To The Bond
    2,962 words
    In my essay on the structure and bonding in different substances, I am going to focus on electronic arrangement and their effects on the properties of the substance. METALIC BONDING Metallic bonding occurs between atoms with low electronegativity (. i.e. 1, 2 or 3 valence electrons); therefore there are many vacancies in valence shell. The crystal lattice of metals consists of ions NOT atoms. When electron clouds overlap, electrons can move into electron cloud of adjoining atoms. The outer elect...
