VALENCE BOND THEORY The ‘mixing’ or ‘blending’ of atomic orbitals to accommodate the spatial requirements in a molecule is known as hybridization. Hybridization occurs to minimize electron pair repulsions when atoms are brought together to form molecules. Possible hybridization schemes: 2nd row elements: sp sp2 sp3 3rd row elements also have: dsp3 d2sp3 Each of these hybridzation schemes corresponds to one of the five fundamental VSEPR geometries. Bonding arises from the overlap

Describe the difference between a mixture and a compound. A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components‚ a compound cannot. Below are some examples of the differences between each. Compounds •Compounds are pure substances. •They are made up of two or more elements

sacrifices in order to keep the department running‚ such as working less hours or even a temporary pay cut. If the team is able to join together and come thru a difficult time they will be more bonded and work more efficiently than ever before. Emotional bonds motivate employees to put forth effort‚ communicate honestly‚ and openly‚ and enable them to handle conflict in a positive manner (Spector‚ 2010). References Spector‚ B. (2010).

elements? A: A large difference in electronegativity between two atoms in a bond will result in ionic bonding. A small difference in electronegativity between two atoms will result in covalent bonding. Translation: Electronegativity difference between 0-0.3 = Non-polar covalent bond Electronegativity difference between 0.3-1.7 = Polar covalent bond Electronegativity difference greater than 1.7 = Ionic bond 3. What type of bonding would be expected between the following atoms?

discrepancies in the prices of multiple long maturity US Treasury bonds seemed to appear in the market. An employee of the firm Mercer and Associates‚ Samantha Thompson‚ thought of a way to exploit this opportunity in order to take advantage of a positive pricing difference by substituting superior bonds for existing holdings. Thompson created two synthetic bonds that imitated the cash flows of the 8¼ May 00-05 bond; one for if the bond had been called at the year 2000‚ and one for if it hadn’t been

INTRODUCTION 1.1 WHAT IS BOND? In finance‚ a bond is an instrument of indebtedness of the bond issuer to the holders. It is a debt security‚ under which the issuer owes the holders a debt and‚ depending on the terms of the bond‚ is obliged to pay them interest (the coupon) and/or to repay the principal at a later date‚ termed the maturity. Interest is usually payable at fixed intervals (semi-annual‚ annual‚ and sometimes monthly). Very often the bond is negotiable‚ i.e. the ownership of the

CHARACTERISTIC OF BONDS AND STOCKS 1.0 Bonds A bond is a promissory note issued by a business or a governmental unit. Treasury bonds‚ sometimes referred to as government bonds‚ are issued by the Federal government and are not exposed to default risk. Corporate bonds are issued by corporations and are exposed to default risk. Different corporate bonds have different levels of default risk‚ depending on the issuing company ’s characteristics and on the terms of the specific bond. Municipal bonds are issued
