1. Forging A World Economy; 1400-1800 Intro Paragraph: The Rise of the West: Scholars tried to explain why political & economic power was concentrated in the hands of Western States (Western Europe & the US). Debates between the two got heated because it concerned the present the future as much as it did the past. A.On one side; Cultural Approach: were those who congratulated today’s winners in the global economy by arguing that the rich were wealthy

METALLIC BONDINGThis page introduces the bonding in metals. It explains how the metallic bond arises and why its strength varies from metal to metal.What is a metallic bond?Metallic bonding in sodiumMetals tend to have high melting points and boiling points suggesting strong bonds between the atoms. Even a metal like sodium (melting point 97.8°C) melts at a considerably higher temperature than the element (neon) which precedes it in the Periodic Table.Sodium has the electronic structure 1s22s22p63s1

Chemistry A Bonding Worksheet #1: Introduction to Ionic Bonds The forces that hold matter together are called chemical bonds. There are four major types of bonds. We need to learn in detail about these bonds and how they influence the properties of matter. The four major types of bonds are: I. Ionic Bonds III. Metallic Bonds II. Covalent Bonds IV. Intermolecular (van der Waals) forces Ionic Bonds The ionic bond is formed by the attraction between oppositely charged ions.

Assessment 1) Describe the difference between ionic and covalent bond. Ionic bonds have electrostatic forces that hold cations and anions together‚ and are electronic neutral. Covalent bonds are bonds that don’t give or take any electrons. In stead they share the elctrons 50) Which of these compounds contain elements that do not follow the octet rule? Explain. a) NF3: 5 + (7*3) = 26 b) PCl2F3: 5 + (7*2) + (7*3) = 40 c) SF4: 6 + (7 *4) = 24 d) SCl2: 6 + (7*2) = 20 The answer is “d”

CLOSED-DIE DROP FORGING (IMPRESSION DIE FORGING) • Closed die drop forging sometimes referred to as impression die forging comprises of a die on the anvil which resembles a mould‚ the ram which falls and strikes the top of the work piece can also be equipped with a die. The metal work piece is heated and placed on the lower die while the ram falls down forcing the metal to fill the contours of the die blocks. • The ram may impact the work several times to ensure all of the contours

Metallic Bonding Metallic Bonding Why do metals conduct electricity? Metals conduct electricity. The delocalised electrons are free to move throughout the structure in 3-dimensions. They can cross grain boundaries. Even though the pattern may be disrupted at the boundary‚ as long as atoms are touching each other‚ the metallic bond is still present. Liquid metals also conduct electricity‚ showing that although the metal atoms may be free to move‚ the delocalisation remains in force until the

FAMILY BONDING The Norman Rockwell family gathered around the table is an image many know. The whole family happily gathered together in anticipation of a shared meal. In the essay‚ “The Magic of the Family Meal”‚ Nancy Gibbs talks about this dying tradition of sitting down with the family to share in a meal. Life is constantly happening around us and sometimes we don’t take the time to sit and enjoy the company of our family‚ the bonds it can create‚ and the benefit it can have on children. Sitting

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 bond
