Chemical bond From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such

NR (no reaction). Before beginning‚ set up a data table similar to the Data Table: Solubility Rules Table in the Lab Report Assistant section. CAUTION! Sodium hydroxide is caustic and can burn skin and clothes if it touches them. Rinse any spills well with copious amounts of water. Also‚ most of these chemicals are toxic by ingestion. So remember‚ no food or drinks in the lab! 1. All reactions will be performed in the 96-well plate. a. Place 2 drops of cobalt (II) nitrate solution into seven

Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic compound

Nomenclature for Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). The nomenclature‚ or naming‚ of ionic compounds is based on the names of the component ions. Here are the principal naming conventions for ionic compounds‚ along with examples to show how they are used: Roman NumeralsA Roman numeral in parentheses‚ followed by the name of the element‚ is used for elements that can form more than one positive ion. This is usually seen with metals. You

What are Yield to Maturity (YTM) and Yield to Call (YTC)? By calculating the present and future value of bonds‚ managers can make sound decisions about their potential strengths and weaknesses as investments. Answer the following questions in this week’s Discussion 2 thread: 1. What terms (or inputs) are needed to calculate yield to maturity (YTM)? How does this compare to calculating yield to call (YTC)? To calculate the YTM you will need to use Annual Interest‚ Par value‚ Market Price

One of the most important aspects to come out of Greek art is the architecture‚ most notable the three architectural orders of ancient Greece‚ Doric‚ Ionic and Corinthian. Each components of this order has a system of inter dependable parts whose proportions are based upon mathematical ratios. The basic components of all three orders are the column and entablature.
