INTRODUCTION TO CHEMICAL BONDS CHEMICAL BOND Definition: A chemical bond is defined as a force that acts between two or more atoms to hold them together as a stable molecule. Main types of bond: 1. Ionic or electrovalent bond‚ 2. Covalent bond‚ 3. Coordinate covalent bond Forth type of bond: Metallic bond: The type of bonding which holds the atoms together in metal crystal. Valence electron: The electrons in the outer most energy level in an atom that takes part in chemical

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

1. The security of the bond‚ that is‚ whether the bond has collateral. Effect on the coupon rate of the bond issue: Bond’s with collateral will have lower coupon rate as bondholders have claim on collateral no matter what. Advantage: It provides an asset which lower default risk. Disadvantage: Companies cannot sell this collateral as an asset and need to maintain it. 2. The seniority of the bond Effect on the coupon rate of the bond issue: The more senior the bond‚ the lower the coupon

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
Premium Electron Atom Covalent bond
Covalent Bonds Covalent bonds are formed when atoms share electrons‚ one from each atom in a single bond‚ to form electron pairs‚ usually making their outermost shells up to eight electrons by this means. This would make them more stable‚ less reactive and an electronic structure like a noble gas. They are most frequently formed between pairs of non-metallic elements. Non-metallic elements usually have from four to eight electrons in their outermost shells‚ the so-called valency electrons‚ which
