  • Electron Distribution In A Bond
    524 words
    Chemical reactions involve the making and breaking of bonds. It is essential that we know what bonds are before we can understand any chemical reaction. To understand bonds, we will first describe several of their properties. The bond strength tells us how hard it is to break a bond. Bond lengths give us valuable structural information about the positions of the atomic nuclei. Bond dipoles inform us about the electron distribution around the two bonded atoms. From bond dipoles we may derive elec...
  • Atoms Bond The Na
    473 words
    Chemical bonds are what make up the world. In bonds, elements are held together and form compounds that may have new physical and chemical properties. There are two main kinds of bonds, they ionic and covalent. In bonding the goal of the atoms involved is to reach a level of stability with less energy. In order to reach the epitome of stability, as in the case of noble gases, an atom strives to complete its outer shell. Either losing or gaining electrons may do this, which concludes in an ionic ...
  • Ionic Compounds Conduct Electricity
    502 words
    Lab: Ionic and Covalent Compounds Pre-Lab 1. List the properties of ionic compounds. - Solids at room temperature. - Soluble in water. - Conduct electricity (while in solution). - Very high melting and boiling points. 2. List the properties of covalent compounds. - Solids, liquids, or gases at room temperature. - May or may not be soluble in water. - Most do not conduct electricity (except for acids) - Low melting and boiling points. 3. Give the name and formula for: a) 3 ionic compounds NaCl-So...
  • Mobile Electrons Between The Layers Metallic Bonding
    506 words
    Element a substance which cannot be broken down into two or more substances by any means. Only contains one type of atom. Compound a substance in which atoms of two or more elements have been chemically combined. Ionic Bonding. Metals bonding with non-metals. Involves transfer of electrons from metal to non-metal, so that both species obtain full outer shell electron configurations (Noble gas configuration)... Metals lose electrons to form positive ions (Cations)... Non-metals gain electrons to ...
  • One Electron From The Bonding Pair
    296 words
    Homologous Series: An homologous series is a set of compounds whose components differ by a single repeating functional group. In the case of (straight chain) alkanes, CH 2. Their general formula is Ch 2 n+2. The chemical properties of the individual members of an homologous series are similar and they show a gradual change in physical properties. Hydrocarbons: Compounds containing only hydrogen and carbon. There are three types alkanes, alkenes and alkyne's. A saturated molecule contains single ...
  • 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...
