by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point‚ solubility‚ and conductivity‚ can be used to predict the type of bond that binds

CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds‚ in

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

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)?

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.

Ionic Bonds Essay The periodic table is a masterpiece of organized chemical information. It is a table of the chemical elements in which the elements are arranged by order of atomic number. The standard form of the table includes periods (horizontal rows in the periodic table) and groups (vertical rows in the periodic table). Atoms are the basic building blocks of ordinary matter. Atoms are made up of particles called protons‚ electrons‚ and neutrons. Protons carry a positive electrical charge‚
